NAME
       cmakevars - Reference of CMake variables.

VARIABLES THAT PROVIDE INFORMATION
       variables defined by cmake, that give information about the project, and cmake

       CMAKE_AR
	      Name of archiving tool for static libraries.

	      This specifies name of the program that creates archive or static libraries.

       CMAKE_ARGC
	      Number of command line arguments passed to CMake in script mode.

	      When run in -P script mode, CMake sets this variable to the number of command line arguments. See also CMAKE_ARGV0, 1, 2 ...

       CMAKE_ARGV0
	      Command line argument passed to CMake in script mode.

	      When run in -P script mode, CMake sets this variable to the first command line argument. It then also sets CMAKE_ARGV1, CMAKE_ARGV2,
	      ... and so on, up to the number of command line arguments given. See also CMAKE_ARGC.

       CMAKE_BINARY_DIR
	      The path to the top level of the build tree.

	      This is the full path to the top level of the current CMake build  tree.	For  an  in-source  build,  this  would  be  the  same	as
	      CMAKE_SOURCE_DIR.

       CMAKE_BUILD_TOOL
	      Tool used for the actual build process.

	      This  variable is set to the program that will be needed to build the output of CMake.   If the generator selected was Visual Studio
	      6, the CMAKE_BUILD_TOOL will be set to msdev, for Unix makefiles it will be set to make or gmake, and for Visual Studio 7 it set	to
	      devenv.	For  Nmake Makefiles the value is nmake. This can be useful for adding special flags and commands based on the final build
	      environment.

       CMAKE_CACHEFILE_DIR
	      The directory with the CMakeCache.txt file.

	      This is the full path to the directory that has the CMakeCache.txt file in it.  This is the same as CMAKE_BINARY_DIR.

       CMAKE_CACHE_MAJOR_VERSION
	      Major version of CMake used to create the CMakeCache.txt file

	      This is stores the major version of CMake used to write a CMake cache file. It is only different when a different version  of  CMake
	      is run on a previously created cache file.

       CMAKE_CACHE_MINOR_VERSION
	      Minor version of CMake used to create the CMakeCache.txt file

	      This  is	stores the minor version of CMake used to write a CMake cache file. It is only different when a different version of CMake
	      is run on a previously created cache file.

       CMAKE_CACHE_PATCH_VERSION
	      Patch version of CMake used to create the CMakeCache.txt file

	      This is stores the patch version of CMake used to write a CMake cache file. It is only different when a different version  of  CMake
	      is run on a previously created cache file.

       CMAKE_CFG_INTDIR
	      Build-time reference to per-configuration output subdirectory.

	      For native build systems supporting multiple configurations in the build tree (such as Visual Studio and Xcode), the value is a ref-
	      erence to a build-time variable specifying the name of the per-configuration output subdirectory.  On Makefile generators this eval-
	      uates to "." because there is only one configuration in a build tree.  Example values:

		$(IntDir)	 = Visual Studio 6
		$(OutDir)	 = Visual Studio 7, 8, 9
		$(Configuration) = Visual Studio 10
		$(CONFIGURATION) = Xcode
		.		 = Make-based tools

	      Since  these  values  are evaluated by the native build system, this variable is suitable only for use in command lines that will be
	      evaluated at build time.	Example of intended usage:

		add_executable(mytool mytool.c)
		add_custom_command(
		  OUTPUT out.txt
		  COMMAND ${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool
			  ${CMAKE_CURRENT_SOURCE_DIR}/in.txt out.txt
		  DEPENDS mytool in.txt
		  )
		add_custom_target(drive ALL DEPENDS out.txt)

	      Note that CMAKE_CFG_INTDIR is no longer necessary for this purpose but has been  left  for  compatibility  with  existing  projects.
	      Instead	 add_custom_command()	 recognizes    executable    target    names	in    its   COMMAND   option,	so   "${CMAKE_CUR-
	      RENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/mytool" can be replaced by just "mytool".

	      This variable is read-only.  Setting it is undefined behavior.  In multi-configuration build systems the value of this  variable	is
	      passed as the value of preprocessor symbol "CMAKE_INTDIR" to the compilation of all source files.

       CMAKE_COMMAND
	      The full path to the cmake executable.

	      This  is	the  full path to the CMake executable cmake which is useful from custom commands that want to use the cmake -E option for
	      portable system commands. (e.g. /usr/local/bin/cmake

       CMAKE_CROSSCOMPILING
	      Is CMake currently cross compiling.

	      This variable will be set to true by CMake if CMake is cross compiling. Specifically if the build platform  is  different  from  the
	      target platform.

       CMAKE_CTEST_COMMAND
	      Full path to ctest command installed with cmake.

	      This  is	the  full path to the CTest executable ctest which is useful from custom commands that want to use the cmake -E option for
	      portable system commands.

       CMAKE_CURRENT_BINARY_DIR
	      The path to the binary directory currently being processed.

	      This the full path to the build directory that is currently being processed by cmake.  Each directory added by add_subdirectory will
	      create  a  binary  directory in the build tree, and as it is being processed this variable will be set. For in-source builds this is
	      the current source directory being processed.

       CMAKE_CURRENT_LIST_DIR
	      Full directory of the listfile currently being processed.

	      As CMake processes the listfiles in your project this variable will always be set to the directory where the listfile which is  cur-
	      rently being processed (CMAKE_CURRENT_LIST_FILE) is located.  The value has dynamic scope.  When CMake starts processing commands in
	      a source file it sets this variable to the directory where this file is located.	When CMake finishes processing commands  from  the
	      file  it	restores  the previous value.  Therefore the value of the variable inside a macro or function is the directory of the file
	      invoking the bottom-most entry on the call stack, not the directory of the file containing the macro or function definition.

	      See also CMAKE_CURRENT_LIST_FILE.

       CMAKE_CURRENT_LIST_FILE
	      Full path to the listfile currently being processed.

	      As CMake processes the listfiles in your project this variable will always be set to the one currently being processed.	The  value
	      has  dynamic scope.  When CMake starts processing commands in a source file it sets this variable to the location of the file.  When
	      CMake finishes processing commands from the file it restores the previous value.	Therefore the value of the variable inside a macro
	      or function is the file invoking the bottom-most entry on the call stack, not the file containing the macro or function definition.

	      See also CMAKE_PARENT_LIST_FILE.

       CMAKE_CURRENT_LIST_LINE
	      The line number of the current file being processed.

	      This is the line number of the file currently being processed by cmake.

       CMAKE_CURRENT_SOURCE_DIR
	      The path to the source directory currently being processed.

	      This the full path to the source directory that is currently being processed by cmake.

       CMAKE_DL_LIBS
	      Name of library containing dlopen and dlcose.

	      The name of the library that has dlopen and dlclose in it, usually -ldl on most UNIX machines.

       CMAKE_EDIT_COMMAND
	      Full path to cmake-gui or ccmake.

	      This is the full path to the CMake executable that can graphically edit the cache.  For example, cmake-gui, ccmake, or cmake -i.

       CMAKE_EXECUTABLE_SUFFIX
	      The suffix for executables on this platform.

	      The suffix to use for the end of an executable if any, .exe on Windows.

	      CMAKE_EXECUTABLE_SUFFIX_<LANG> overrides this for language <LANG>.

       CMAKE_EXTRA_GENERATOR
	      The extra generator used to build the project.

	      When  using  the	Eclipse,  CodeBlocks  or KDevelop generators, CMake generates Makefiles (CMAKE_GENERATOR) and additionally project
	      files for the respective IDE. This IDE project file generator is stored in CMAKE_EXTRA_GENERATOR (e.g. "Eclipse CDT4").

       CMAKE_EXTRA_SHARED_LIBRARY_SUFFIXES
	      Additional suffixes for shared libraries.

	      Extensions for shared libraries other than that specified by CMAKE_SHARED_LIBRARY_SUFFIX, if any.   CMake  uses  this  to  recognize
	      external shared library files during analysis of libraries linked by a target.

       CMAKE_GENERATOR
	      The generator used to build the project.

	      The name of the generator that is being used to generate the build files.  (e.g. "Unix Makefiles", "Visual Studio 6", etc.)

       CMAKE_HOME_DIRECTORY
	      Path to top of source tree.

	      This is the path to the top level of the source tree.

       CMAKE_IMPORT_LIBRARY_PREFIX
	      The prefix for import libraries that you link to.

	      The prefix to use for the name of an import library if used on this platform.

	      This variable is around for backwards compatibility, see CMAKE_BUILD_TOOL.

       CMAKE_MINOR_VERSION
	      The Minor version of cmake (i.e. the 4 in X.4.X).

	      This specifies the minor version of the CMake executable being run.

       CMAKE_PARENT_LIST_FILE
	      Full path to the parent listfile of the one currently being processed.

	      As  CMake  processes the listfiles in your project this variable will always be set to the listfile that included or somehow invoked
	      the one currently being processed. See also CMAKE_CURRENT_LIST_FILE.

       CMAKE_PATCH_VERSION
	      The patch version of cmake (i.e. the 3 in X.X.3).

	      This specifies the patch version of the CMake executable being run.

       CMAKE_PROJECT_NAME
	      The name of the current project.

	      This specifies name of the current project from the closest inherited PROJECT command.

       CMAKE_RANLIB
	      Name of randomizing tool for static libraries.

	      This specifies name of the program that randomizes libraries on UNIX, not used on Windows, but may be present.

       CMAKE_ROOT
	      Install directory for running cmake.

	      This is the install root for the running CMake and the Modules directory can be found here. This is commonly used  in  this  format:
	      ${CMAKE_ROOT}/Modules

       CMAKE_SCRIPT_MODE_FILE
	      Full path to the -P script file currently being processed.

	      When  run  in  -P  script mode, CMake sets this variable to the full path of the script file. When run to configure a CMakeLists.txt
	      file, this variable is not set.

       CMAKE_SHARED_LIBRARY_PREFIX
	      The prefix for shared libraries that you link to.

	      The prefix to use for the name of a shared library, lib on UNIX.

	      CMAKE_SHARED_LIBRARY_PREFIX_<LANG> overrides this for language <LANG>.

	      The suffix for shared libraries that you link to.

	      The suffix to use for the end of a shared library, .dll on Windows.

	      CMAKE_SHARED_LIBRARY_SUFFIX_<LANG> overrides this for language <LANG>.

       CMAKE_SHARED_MODULE_PREFIX
	      The prefix for loadable modules that you link to.

	      The prefix to use for the name of a loadable module on this platform.

	      CMAKE_SHARED_MODULE_PREFIX_<LANG> overrides this for language <LANG>.

       CMAKE_SHARED_MODULE_SUFFIX
	      The suffix for shared libraries that you link to.

	      The suffix to use for the end of a loadable module on this platform

	      CMAKE_SHARED_MODULE_SUFFIX_<LANG> overrides this for language <LANG>.

       CMAKE_SIZEOF_VOID_P
	      Size of a void pointer.

	      This is set to the size of a pointer on the machine, and is determined by a try compile. If a 64 bit size is found, then the library
	      search path is modified to look for 64 bit libraries first.

       CMAKE_SKIP_RPATH
	      If true, do not add run time path information.

	      If this is set to TRUE, then the rpath information is not added to compiled executables.	The default is to add rpath information if
	      the platform supports it.  This allows for easy running from the build tree.  To omit RPATH in the install step, but not	the  build
	      step, use CMAKE_SKIP_INSTALL_RPATH instead.

       CMAKE_SOURCE_DIR
	      The path to the top level of the source tree.

	      This  is	the  full  path  to  the  top  level  of  the current CMake source tree. For an in-source build, this would be the same as
	      CMAKE_BINARY_DIR.

       CMAKE_STANDARD_LIBRARIES
	      Libraries linked into every executable and shared library.

	      This is the list of libraries that are linked into all executables and libraries.

       CMAKE_STATIC_LIBRARY_PREFIX
	      The prefix for static libraries that you link to.

	      The prefix to use for the name of a static library, lib on UNIX.

	      CMAKE_STATIC_LIBRARY_PREFIX_<LANG> overrides this for language <LANG>.

       CMAKE_STATIC_LIBRARY_SUFFIX
	      The suffix for static libraries that you link to.

	      The suffix to use for the end of a static library, .lib on Windows.

	      CMAKE_STATIC_LIBRARY_SUFFIX_<LANG> overrides this for language <LANG>.

       CMAKE_TWEAK_VERSION
	      The tweak version of cmake (i.e. the 1 in X.X.X.1).

	      This specifies the tweak version of the CMake executable being run.  Releases use tweak < 20000000 and development versions use  the
	      date format CCYYMMDD for the tweak level.

       CMAKE_USING_VC_FREE_TOOLS
	      True if free visual studio tools being used.

	      This is set to true if the compiler is Visual Studio free tools.

       CMAKE_VERBOSE_MAKEFILE
	      Create verbose makefiles if on.

	      This  variable  defaults	to false. You can set this variable to true to make CMake produce verbose makefiles that show each command
	      line as it is used.

       CMAKE_VERSION
	      The full version of cmake in major.minor.patch[.tweak[-id]] format.

	      This specifies the full version of the CMake executable being run.  This variable is defined by  versions  2.6.3	and  higher.   See
	      variables  CMAKE_MAJOR_VERSION, CMAKE_MINOR_VERSION, CMAKE_PATCH_VERSION, and CMAKE_TWEAK_VERSION for individual version components.
	      The [-id] component appears in non-release versions and may be arbitrary text.

       PROJECT_BINARY_DIR
	      Full path to build directory for project.

	      This is the binary directory of the most recent PROJECT command.

       PROJECT_NAME
	      Name of the project given to the project command.

	      This is the name given to the most recent PROJECT command.

       PROJECT_SOURCE_DIR
	      Top level source directory for the current project.

	      This is the source directory of the most recent PROJECT command.

       [Project name]_BINARY_DIR
	      Top level binary directory for the named project.

	      A variable is created with the name used in the PROJECT command, and is the binary directory for the project.   This can	be  useful
	      when SUBDIR is used to connect several projects.

       [Project name]_SOURCE_DIR
	      Top level source directory for the named project.

	      A  variable  is created with the name used in the PROJECT command, and is the source directory for the project.	This can be useful
	      when add_subdirectory is used to connect several projects.

VARIABLES THAT CHANGE BEHAVIOR
       BUILD_SHARED_LIBS
	      Global flag to cause add_library to create shared libraries if on.

	      If present and true, this will cause all libraries to be built shared unless the library was explicitly added as a  static  library.
	      This  variable  is  often added to projects as an OPTION so that each user of a project can decide if they want to build the project
	      using shared or static libraries.

       CMAKE_ABSOLUTE_DESTINATION_FILES
	      List of files which have been installed using  an ABSOLUTE DESTINATION path.

	      This variable is defined by CMake-generated cmake_install.cmake scripts. It can be used (read-only) by program or script that source
	      those install scripts. This is used by some CPack generators (e.g. RPM).

       CMAKE_AUTOMOC_RELAXED_MODE
	      Switch between strict and relaxed automoc mode.

	      By  default, automoc behaves exactly as described in the documentation of the AUTOMOC target property.  When set to TRUE, it accepts
	      more input and tries to find the correct input file for moc even if it differs from the documented behaviour. In this mode  it  e.g.
	      also checks whether a header file is intended to be processed by moc when a "foo.moc" file has been included.

	      Relaxed mode has to be enabled for KDE4 compatibility.

       CMAKE_BACKWARDS_COMPATIBILITY
	      Version of cmake required to build project

	      From  the  point of view of backwards compatibility, this specifies what version of CMake should be supported. By default this value
	      is the version number of CMake that you are running. You can set this to an older version of CMake to support deprecated commands of
	      CMake  in projects that were written to use older versions of CMake. This can be set by the user or set at the beginning of a CMake-
	      Lists file.

       CMAKE_BUILD_TYPE
	      Specifies the build type for make based generators.

	      This specifies what build type will be built in this tree.  Possible values are empty, Debug, Release,  RelWithDebInfo  and  MinSiz-
	      eRel. This variable is only supported for make based generators. If this variable is supported, then CMake will also provide initial
	      values for the variables with the name  CMAKE_C_FLAGS_[DEBUG|RELEASE|RELWITHDEBINFO|MINSIZEREL]. For example, if CMAKE_BUILD_TYPE is
	      Debug, then CMAKE_C_FLAGS_DEBUG will be added to the CMAKE_C_FLAGS.

       CMAKE_COLOR_MAKEFILE
	      Enables color output when using the Makefile generator.

	      When enabled, the generated Makefiles will produce colored output. Default is ON.

       CMAKE_CONFIGURATION_TYPES
	      Specifies the available build types.

	      This  specifies  what build types will be available such as Debug, Release, RelWithDebInfo etc. This has reasonable defaults on most
	      platforms. But can be extended to provide other build types. See also CMAKE_BUILD_TYPE.

       CMAKE_DISABLE_FIND_PACKAGE_<PackageName>
	      Variable for disabling find_package() calls.

	      Every non-REQUIRED find_package() call in a project can be disabled by setting the variable CMAKE_DISABLE_FIND_PACKAGE_<PackageName>
	      to TRUE. This can be used to build a project without an optional package, although that package is installed.

	      This  switch  should  be used during the initial CMake run. Otherwise if the package has already been found in a previous CMake run,
	      the variables which have been stored in the cache will still be there. In the case it is recommended to remove the  cache  variables
	      for this package from the cache using the cache editor or cmake -U

       CMAKE_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION
	      Ask cmake_install.cmake script to error out as soon as a file with absolute INSTALL DESTINATION is encountered.

	      The  fatal  error  is  emitted  before  the installation of the offending file takes place. This variable is used by CMake-generated
	      cmake_install.cmake scripts. If ones set this variable to ON while running the script, it may get  fatal	error  messages  from  the
	      script.

       CMAKE_FIND_LIBRARY_PREFIXES
	      Prefixes to prepend when looking for libraries.

	      This specifies what prefixes to add to library names when the find_library command looks for libraries. On UNIX systems this is typ-
	      ically lib, meaning that when trying to find the foo library it will look for libfoo.

       CMAKE_FIND_LIBRARY_SUFFIXES
	      Suffixes to append when looking for libraries.

	      This specifies what suffixes to add to library names when the find_library command looks for libraries. On Windows systems  this	is
	      typically .lib and .dll, meaning that when trying to find the foo library it will look for foo.dll etc.

       CMAKE_FIND_PACKAGE_WARN_NO_MODULE
	      Tell find_package to warn if called without an explicit mode.

	      If  find_package	is  called  without  an  explicit  mode  option  (MODULE, CONFIG or NO_MODULE) and no Find<pkg>.cmake module is in
	      CMAKE_MODULE_PATH then CMake implicitly assumes that the caller intends to search for a package configuration file.  If  no  package
	      configuration  file is found then the wording of the failure message must account for both the case that the package is really miss-
	      ing and the case that the project has a bug and failed to provide the intended Find module.  If  instead	the  caller  specifies	an
	      explicit mode option then the failure message can be more specific.

	      Set  CMAKE_FIND_PACKAGE_WARN_NO_MODULE  to  TRUE	to  tell  find_package to warn when it implicitly assumes Config mode.	This helps
	      developers enforce use of an explicit mode in all calls to find_package within a project.

       CMAKE_IGNORE_PATH
	      Path to be ignored by FIND_XXX() commands.

	      Specifies directories to be ignored by searches in FIND_XXX() commands This is useful in cross-compiled environments where some sys-
	      tem  directories	contain  incompatible  but  possibly linkable libraries. For example, on cross-compiled cluster environments, this
	      allows a user to ignore directories containing libraries meant for the front-end machine that  modules  like  FindX11  (and  others)
	      would  normally  search. By default this is empty; it is intended to be set by the project. Note that CMAKE_IGNORE_PATH takes a list
	      of directory names, NOT a list of prefixes. If you want to ignore paths under prefixes (bin, include, lib,  etc.),  you'll  need	to
	      specify them explicitly. See also CMAKE_PREFIX_PATH, CMAKE_LIBRARY_PATH, CMAKE_INCLUDE_PATH, CMAKE_PROGRAM_PATH.

       CMAKE_INCLUDE_PATH
	      Path used for searching by FIND_FILE() and FIND_PATH().

	      Specifies  a path which will be used both by FIND_FILE() and FIND_PATH(). Both commands will check each of the contained directories
	      for the existence of the file which is currently searched. By default it is empty, it is intended to be set by the project. See also
	      CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_PREFIX_PATH.

       CMAKE_INSTALL_DEFAULT_COMPONENT_NAME
	      Default component used in install() commands.

	      If  an  install()  command is used without the COMPONENT argument, these files will be grouped into a default component. The name of
	      this default install component will be taken from this variable.	It defaults to "Unspecified".

       CMAKE_INSTALL_PREFIX
	      Install directory used by install.

	      If "make install" is invoked or INSTALL is built, this directory is pre-pended onto all install directories. This variable  defaults
	      to /usr/local on UNIX and c:/Program Files on Windows.

       CMAKE_LIBRARY_PATH
	      Path used for searching by FIND_LIBRARY().

	      Specifies a path which will be used by FIND_LIBRARY(). FIND_LIBRARY() will check each of the contained directories for the existence
	      of the library which is currently searched. By default it is empty, it is intended to be set by the  project.  See  also	CMAKE_SYS-
	      TEM_LIBRARY_PATH, CMAKE_PREFIX_PATH.

       CMAKE_MFC_FLAG
	      Tell cmake to use MFC for an executable or dll.

	      This  can  be  set in a CMakeLists.txt file and will enable MFC in the application.  It should be set to 1 for static the static MFC
	      library, and 2 for the shared MFC library.  This is used in visual studio 6 and 7 project files.	 The CMakeSetup  dialog  used  MFC
	      and the CMakeLists.txt looks like this:

	      add_definitions(-D_AFXDLL)

	      set(CMAKE_MFC_FLAG 2)

	      add_executable(CMakeSetup WIN32 ${SRCS})

       CMAKE_MODULE_PATH
	      List of directories to search for CMake modules.

	      Commands	like include() and find_package() search for files in directories listed by this variable before checking the default mod-
	      ules that come with CMake.

       CMAKE_NOT_USING_CONFIG_FLAGS
	      Skip _BUILD_TYPE flags if true.

	      This is an internal flag used by the generators in CMake to tell CMake to skip the _BUILD_TYPE flags.

       CMAKE_POLICY_DEFAULT_CMP<NNNN>
	      Default for CMake Policy CMP<NNNN> when it is otherwise left unset.

	      Commands cmake_minimum_required(VERSION) and cmake_policy(VERSION) by default leave policies  introduced	after  the  given  version
	      unset.   Set  CMAKE_POLICY_DEFAULT_CMP<NNNN>  to	OLD or NEW to specify the default for policy CMP<NNNN>, where <NNNN> is the policy
	      number.

	      This variable should not be set by a project in CMake code; use cmake_policy(SET) instead.  Users running CMake may set  this  vari-
	      able in the cache (e.g. -DCMAKE_POLICY_DEFAULT_CMP<NNNN>=<OLD|NEW>) to set a policy not otherwise set by the project.  Set to OLD to
	      quiet a policy warning while using old behavior or to NEW to try building the project with new behavior.

       CMAKE_PREFIX_PATH
	      Path used for searching by FIND_XXX(), with appropriate suffixes added.

	      Specifies a path which will be used by the FIND_XXX() commands. It contains the "base" directories, the FIND_XXX()  commands  append
	      appropriate  subdirectories  to  the  base  directories.	So  FIND_PROGRAM()  adds  /bin	to  each  of  the directories in the path,
	      FIND_LIBRARY() appends /lib to each of the directories, and FIND_PATH() and FIND_FILE() append /include . By default it is empty, it
	      is intended to be set by the project. See also CMAKE_SYSTEM_PREFIX_PATH, CMAKE_INCLUDE_PATH, CMAKE_LIBRARY_PATH, CMAKE_PROGRAM_PATH.

       CMAKE_PROGRAM_PATH
	      Path used for searching by FIND_PROGRAM().

	      Specifies a path which will be used by FIND_PROGRAM(). FIND_PROGRAM() will check each of the contained directories for the existence
	      of the program which is currently searched. By default it is empty, it is intended to be set by the  project.  See  also	CMAKE_SYS-
	      TEM_PROGRAM_PATH,  CMAKE_PREFIX_PATH.

       CMAKE_SKIP_INSTALL_ALL_DEPENDENCY
	      Don't make the install target depend on the all target.

	      By default, the "install" target depends on the "all" target. This has the effect, that when "make install" is invoked or INSTALL is
	      built, first the "all" target is built, then the installation starts. If CMAKE_SKIP_INSTALL_ALL_DEPENDENCY  is  set  to  TRUE,  this
	      dependency  is  not  created, so the installation process will start immediately, independent from whether the project has been com-
	      pletely built or not.

       CMAKE_SYSTEM_IGNORE_PATH
	      Path to be ignored by FIND_XXX() commands.

	      Specifies directories to be ignored by searches in FIND_XXX() commands This is useful in cross-compiled environments where some sys-
	      tem  directories	contain  incompatible  but  possibly linkable libraries. For example, on cross-compiled cluster environments, this
	      allows a user to ignore directories containing libraries meant for the front-end machine that  modules  like  FindX11  (and  others)
	      would normally search. By default this contains a list of directories containing incompatible binaries for the host system. See also
	      CMAKE_SYSTEM_PREFIX_PATH, CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_SYSTEM_INCLUDE_PATH, and CMAKE_SYSTEM_PROGRAM_PATH.

       CMAKE_SYSTEM_INCLUDE_PATH
	      Path used for searching by FIND_FILE() and FIND_PATH().

	      Specifies a path which will be used both by FIND_FILE() and FIND_PATH(). Both commands will check each of the contained  directories
	      for  the	existence of the file which is currently searched. By default it contains the standard directories for the current system.
	      It is NOT intended to be modified by the project, use CMAKE_INCLUDE_PATH for this. See also CMAKE_SYSTEM_PREFIX_PATH.

       CMAKE_SYSTEM_LIBRARY_PATH
	      Path used for searching by FIND_LIBRARY().

	      Specifies a path which will be used by FIND_LIBRARY(). FIND_LIBRARY() will check each of the contained directories for the existence
	      of  the  library	which  is  currently  searched.  By default it contains the standard directories for the current system. It is NOT
	      intended to be modified by the project, use CMAKE_LIBRARY_PATH for this. See also CMAKE_SYSTEM_PREFIX_PATH.

       CMAKE_SYSTEM_PREFIX_PATH
	      Path used for searching by FIND_XXX(), with appropriate suffixes added.

	      Specifies a path which will be used by the FIND_XXX() commands. It contains the "base" directories, the FIND_XXX()  commands  append
	      appropriate  subdirectories  to  the  base  directories.	So  FIND_PROGRAM()  adds  /bin	to  each  of  the directories in the path,
	      FIND_LIBRARY() appends /lib to each of the directories, and FIND_PATH() and FIND_FILE() append /include . By default  this  contains
	      the  standard  directories for the current system. It is NOT intended to be modified by the project, use CMAKE_PREFIX_PATH for this.
	      See also CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_SYSTEM_PROGRAM_PATH, and CMAKE_SYSTEM_IGNORE_PATH.

       CMAKE_SYSTEM_PROGRAM_PATH
	      Path used for searching by FIND_PROGRAM().

	      Specifies a path which will be used by FIND_PROGRAM(). FIND_PROGRAM() will check each of the contained directories for the existence
	      of  the  program	which  is  currently  searched.  By default it contains the standard directories for the current system. It is NOT
	      intended to be modified by the project, use CMAKE_PROGRAM_PATH for this. See also CMAKE_SYSTEM_PREFIX_PATH.

       CMAKE_USER_MAKE_RULES_OVERRIDE
	      Specify a CMake file that overrides platform information.

	      CMake loads the specified file while enabling support for each language from either the project() or enable_language() commands.	It
	      is  loaded after CMake's builtin compiler and platform information modules have been loaded but before the information is used.  The
	      file may set platform information variables to override CMake's defaults.

	      This feature is intended for use only in overriding information variables that must be  set  before  CMake  builds  its  first  test
	      project to check that the compiler for a language works.	It should not be used to load a file in cases that a normal include() will
	      work.  Use it only as a last resort for behavior that cannot be achieved any other way.  For example, one may set CMAKE_C_FLAGS_INIT
	      to  change the default value used to initialize CMAKE_C_FLAGS before it is cached.  The override file should NOT be used to set any-
	      thing that could be set after languages are enabled, such as variables like CMAKE_RUNTIME_OUTPUT_DIRECTORY that affect the placement
	      of binaries.  Information set in the file will be used for try_compile and try_run builds too.

       CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION
	      Ask cmake_install.cmake script to warn each time a file with absolute INSTALL DESTINATION is encountered.

	      This  variable  is used by CMake-generated cmake_install.cmake scripts. If ones set this variable to ON while running the script, it
	      may get warning messages from the script.

VARIABLES THAT DESCRIBE THE SYSTEM
       APPLE  True if running on Mac OSX.

	      Set to true on Mac OSX.

       BORLAND
	      True if the borland compiler is being used.

	      This is set to true if the Borland compiler is being used.

       CMAKE_CL_64
	      Using the 64 bit compiler from Microsoft

	      Set to true when using the 64 bit cl compiler from Microsoft.

       CMAKE_COMPILER_2005
	      Using the Visual Studio 2005 compiler from Microsoft

	      Set to true when using the Visual Studio 2005 compiler from Microsoft.

       CMAKE_HOST_APPLE
	      True for Apple OSXoperating systems.

	      Set to true when the host system is Apple OSX.

       CMAKE_HOST_SYSTEM
	      Name of system cmake is being run on.

	      The same as CMAKE_SYSTEM but for the host system instead of the target system when cross compiling.

       CMAKE_HOST_SYSTEM_NAME
	      Name of the OS CMake is running on.

	      The same as CMAKE_SYSTEM_NAME but for the host system instead of the target system when cross compiling.

       CMAKE_HOST_SYSTEM_PROCESSOR
	      The name of the CPU CMake is running on.

	      The same as CMAKE_SYSTEM_PROCESSOR but for the host system instead of the target system when cross compiling.

       CMAKE_HOST_SYSTEM_VERSION
	      OS version CMake is running on.

	      The same as CMAKE_SYSTEM_VERSION but for the host system instead of the target system when cross compiling.

       CMAKE_HOST_UNIX
	      True for UNIX and UNIX like operating systems.

	      Set to true when the host system is UNIX or UNIX like (i.e. APPLE and CYGWIN).

       CMAKE_HOST_WIN32
	      True on windows systems, including win64.

	      Set to true when the host system is Windows and on cygwin.

       CMAKE_LIBRARY_ARCHITECTURE
	      Target architecture library directory name, if detected.

	      This is the value of CMAKE_<lang>_LIBRARY_ARCHITECTURE as detected for one of the enabled languages.

       CMAKE_LIBRARY_ARCHITECTURE_REGEX
	      Regex matching possible target architecture library directory names.

	      This is used to detect CMAKE_<lang>_LIBRARY_ARCHITECTURE from the implicit linker search path by matching the <arch> name.

       CMAKE_OBJECT_PATH_MAX
	      Maximum object file full-path length allowed by native build tools.

	      CMake computes for every source file an object file name that is unique to the source file and deterministic  with  respect  to  the
	      full  path to the source file.  This allows multiple source files in a target to share the same name if they lie in different direc-
	      tories without rebuilding when one is added or removed.  However, it can produce long full paths in a few cases, so  CMake  shortens
	      the  path using a hashing scheme when the full path to an object file exceeds a limit.  CMake has a built-in limit for each platform
	      that is sufficient for common tools, but some native tools may have a lower limit.  This variable may be set to  specify	the  limit
	      explicitly.  The value must be an integer no less than 128.

       CMAKE_SYSTEM
	      Name of system cmake is compiling for.

	      This  variable  is  the  composite of CMAKE_SYSTEM_NAME and CMAKE_SYSTEM_VERSION, like this ${CMAKE_SYSTEM_NAME}-${CMAKE_SYSTEM_VER-
	      SION}. If CMAKE_SYSTEM_VERSION is not set, then CMAKE_SYSTEM is the same as CMAKE_SYSTEM_NAME.

       CMAKE_SYSTEM_NAME
	      Name of the OS CMake is building for.

	      This is the name of the operating system on which CMake is targeting.   On systems that have the uname command, this variable is set
	      to the output of uname -s.  Linux, Windows,  and Darwin for Mac OSX are the values found	on the big three operating systems.

       CMAKE_SYSTEM_PROCESSOR
	      The name of the CPU CMake is building for.

	      On  systems that support uname, this variable is set to the output of uname -p, on windows it is set to the value of the environment
	      variable PROCESSOR_ARCHITECTURE

       CMAKE_SYSTEM_VERSION
	      OS version CMake is building for.

	      A numeric version string for the system, on systems that support uname, this variable is set to the output of  uname  -r.  On  other
	      systems this is set to major-minor version numbers.

       CYGWIN True for cygwin.

	      Set to true when using CYGWIN.

       MSVC   True when using Microsoft Visual C

	      Set to true when the compiler is some version of Microsoft Visual C.

       MSVC80 True when using Microsoft Visual C 8.0

	      Set to true when the compiler is version 8.0 of Microsoft Visual C.

       MSVC_IDE
	      True when using the Microsoft Visual C IDE

	      Set to true when the target platform is the Microsoft Visual C IDE, as opposed to the command line compiler.

       MSVC_VERSION
	      The version of Microsoft Visual C/C++ being used if any.

	      Known version numbers are:

		1200 = VS  6.0
		1300 = VS  7.0
		1310 = VS  7.1
		1400 = VS  8.0
		1500 = VS  9.0
		1600 = VS 10.0

       UNIX   True for UNIX and UNIX like operating systems.

	      Set to true when the target system is UNIX or UNIX like (i.e. APPLE and CYGWIN).

       WIN32  True on windows systems, including win64.

	      Set to true when the target system is Windows.

       XCODE_VERSION
	      Version of Xcode (Xcode generator only).

	      Under the Xcode generator, this is the version of Xcode as specified in "Xcode.app/Contents/version.plist" (such as "3.1.2").

VARIABLES THAT CONTROL THE BUILD
       CMAKE_<CONFIG>_POSTFIX
	      Default filename postfix for libraries under configuration <CONFIG>.

	      When a non-executable target is created its <CONFIG>_POSTFIX target property is initialized with the value of this variable if it is
	      set.

       CMAKE_ARCHIVE_OUTPUT_DIRECTORY
	      Where to put all the ARCHIVE targets when built.

	      This variable is used to initialize the ARCHIVE_OUTPUT_DIRECTORY property on all the targets. See that  target  property	for  addi-
	      tional information.

       CMAKE_AUTOMOC
	      Whether to handle moc automatically for Qt targets.

	      This variable is used to initialize the AUTOMOC property on all the targets. See that target property for additional information.

       CMAKE_AUTOMOC_MOC_OPTIONS
	      Additional options for moc when using automoc (see CMAKE_AUTOMOC).

	      This  variable  is  used	to initialize the AUTOMOC_MOC_OPTIONS property on all the targets. See that target property for additional
	      information.

       CMAKE_BUILD_WITH_INSTALL_RPATH
	      Use the install path for the RPATH

	      Normally CMake uses the build tree for the RPATH when building executables etc on systems that  use  RPATH.  When  the  software	is
	      installed  the executables etc are relinked by CMake to have the install RPATH. If this variable is set to true then the software is
	      always built with the install path for the RPATH and does not need to be relinked when installed.

       CMAKE_DEBUG_POSTFIX
	      See variable CMAKE_<CONFIG>_POSTFIX.

	      This variable is a special case of the more-general CMAKE_<CONFIG>_POSTFIX variable for the DEBUG configuration.

       CMAKE_EXE_LINKER_FLAGS
	      Linker flags used to create executables.

	      Flags used by the linker when creating an executable.

       CMAKE_EXE_LINKER_FLAGS_[CMAKE_BUILD_TYPE]
	      Flag used when linking an executable.

	      Same as CMAKE_C_FLAGS_* but used by the linker when creating executables.

       CMAKE_Fortran_FORMAT
	      Set to FIXED or FREE to indicate the Fortran source layout.

	      This variable is used to initialize the Fortran_FORMAT property on all the targets. See that target property for additional informa-
	      tion.

       CMAKE_Fortran_MODULE_DIRECTORY
	      Fortran module output directory.

	      This  variable  is  used	to initialize the Fortran_MODULE_DIRECTORY property on all the targets. See that target property for addi-
	      tional information.

       CMAKE_GNUtoMS
	      Convert GNU import libraries (.dll.a) to MS format (.lib).

	      This variable is used to initialize the GNUtoMS property on targets when they are created.  See that target property for	additional
	      information.

       CMAKE_INCLUDE_CURRENT_DIR
	      Automatically add the current source- and build directories to the include path.

	      If  this variable is enabled, CMake automatically adds in each directory ${CMAKE_CURRENT_SOURCE_DIR} and ${CMAKE_CURRENT_BINARY_DIR}
	      to the include path for this directory. These additional include directories do not propagate down to subdirectories. This is useful
	      mainly for out-of-source builds, where files generated into the build tree are included by files located in the source tree.

	      By default CMAKE_INCLUDE_CURRENT_DIR is OFF.

       CMAKE_INSTALL_NAME_DIR
	      Mac OSX directory name for installed targets.

	      CMAKE_INSTALL_NAME_DIR  is used to initialize the INSTALL_NAME_DIR property on all targets. See that target property for more infor-
	      mation.

       CMAKE_INSTALL_RPATH
	      The rpath to use for installed targets.

	      A semicolon-separated list specifying the rpath to use in installed targets (for platforms that support it). This is  used  to  ini-
	      tialize the target property INSTALL_RPATH for all targets.

       CMAKE_INSTALL_RPATH_USE_LINK_PATH
	      Add paths to linker search and installed rpath.

	      CMAKE_INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true will append directories in the linker search path and outside the
	      project to the INSTALL_RPATH. This is used to initialize the target property INSTALL_RPATH_USE_LINK_PATH for all targets.

       CMAKE_LIBRARY_OUTPUT_DIRECTORY
	      Where to put all the LIBRARY targets when built.

	      This variable is used to initialize the LIBRARY_OUTPUT_DIRECTORY property on all the targets. See that  target  property	for  addi-
	      tional information.

       CMAKE_LIBRARY_PATH_FLAG
	      The flag used to add a library search path to a compiler.

	      The flag used to specify a library directory to the compiler. On most compilers this is "-L".

       CMAKE_LINK_DEF_FILE_FLAG
	      Linker flag used to specify a .def file for dll creation.

	      The flag used to add a .def file when creating a dll on Windows, this is only defined on Windows.

       CMAKE_LINK_INTERFACE_LIBRARIES
	      Default value for LINK_INTERFACE_LIBRARIES of targets.

	      This  variable  is  used	to initialize the LINK_INTERFACE_LIBRARIES property on all the targets. See that target property for addi-
	      tional information.

       CMAKE_LINK_LIBRARY_FILE_FLAG
	      Flag used to link a library specified by a path to its file.

	      The flag used before a library file path is given to the linker.	This is needed only on very few platforms.

       CMAKE_LINK_LIBRARY_FLAG
	      Flag used to link a library into an executable.

	      The flag used to specify a library to link to an executable.  On most compilers this is "-l".

       CMAKE_MACOSX_BUNDLE
	      Default value for MACOSX_BUNDLE of targets.

	      This variable is used to initialize the MACOSX_BUNDLE property on all the targets. See that target property for additional  informa-
	      tion.

       CMAKE_NO_BUILTIN_CHRPATH
	      Do not use the builtin ELF editor to fix RPATHs on installation.

	      When an ELF binary needs to have a different RPATH after installation than it does in the build tree, CMake uses a builtin editor to
	      change the RPATH in the installed copy.  If this variable is set to true then CMake  will  relink  the  binary  before  installation
	      instead of using its builtin editor.

       CMAKE_POSITION_INDEPENDENT_FLAGS
	      Default value for POSITION_INDEPENDENT_CODE of targets.

	      This  variable  is  used to initialize the POSITION_INDEPENDENT_CODE property on all the targets. See that target property for addi-
	      tional information.

       CMAKE_RUNTIME_OUTPUT_DIRECTORY
	      Where to put all the RUNTIME targets when built.

	      This variable is used to initialize the RUNTIME_OUTPUT_DIRECTORY property on all the targets. See that  target  property	for  addi-
	      tional information.

       CMAKE_SKIP_BUILD_RPATH
	      Do not include RPATHs in the build tree.

	      Normally	CMake  uses  the  build  tree  for the RPATH when building executables etc on systems that use RPATH. When the software is
	      installed the executables etc are relinked by CMake to have the install RPATH. If this variable is set to true then the software	is
	      always built with no RPATH.

       CMAKE_SKIP_INSTALL_RPATH
	      Do not include RPATHs in the install tree.

	      Normally	CMake  uses  the  build  tree  for the RPATH when building executables etc on systems that use RPATH. When the software is
	      installed the executables etc are relinked by CMake to have the install RPATH. If this variable is set to true then the software	is
	      always  installed without RPATH, even if RPATH is enabled when building.	This can be useful for example to allow running tests from
	      the build directory with RPATH enabled before the installation step.  To omit RPATH  in  both  the  build  and  install  steps,  use
	      CMAKE_SKIP_RPATH instead.

       CMAKE_TRY_COMPILE_CONFIGURATION
	      Build configuration used for try_compile and try_run projects.

	      Projects	built  by try_compile and try_run are built synchronously during the CMake configuration step.	Therefore a specific build
	      configuration must be chosen even if the generated build system supports multiple configurations.

       CMAKE_USE_RELATIVE_PATHS
	      Use relative paths (May not work!).

	      If this is set to TRUE, then the CMake will use relative paths between the source and binary tree. This option  does  not  work  for
	      more  complicated projects, and relative paths are used when possible.  In general, it is not possible to move CMake generated make-
	      files to a different location regardless of the value of this variable.

       CMAKE_WIN32_EXECUTABLE
	      Default value for WIN32_EXECUTABLE of targets.

	      This variable is used to initialize the WIN32_EXECUTABLE property on all the targets. See that target property for additional infor-
	      mation.

       EXECUTABLE_OUTPUT_PATH
	      Old executable location variable.

	      The  target  property RUNTIME_OUTPUT_DIRECTORY supercedes this variable for a target if it is set.  Executable targets are otherwise
	      placed in this directory.

       LIBRARY_OUTPUT_PATH
	      Old library location variable.

	      The target properties ARCHIVE_OUTPUT_DIRECTORY, LIBRARY_OUTPUT_DIRECTORY, and RUNTIME_OUTPUT_DIRECTORY supercede this variable for a
	      target if they are set.  Library targets are otherwise placed in this directory.

VARIABLES FOR LANGUAGES
       CMAKE_<LANG>_ARCHIVE_APPEND
	      Rule variable to append to a static archive.

	      This  is	a  rule  variable  that  tells	CMake  how  to	append	to  a  static  archive.   It is used in place of CMAKE_<LANG>_CRE-
	      ATE_STATIC_LIBRARY on  some  platforms  in  order  to  support  large  object  counts.   See  also  CMAKE_<LANG>_ARCHIVE_CREATE  and
	      CMAKE_<LANG>_ARCHIVE_FINISH.

       CMAKE_<LANG>_ARCHIVE_CREATE
	      Rule variable to create a new static archive.

	      This  is a rule variable that tells CMake how to create a static archive.  It is used in place of CMAKE_<LANG>_CREATE_STATIC_LIBRARY
	      on some platforms in order to support large object counts.  See also CMAKE_<LANG>_ARCHIVE_APPEND and CMAKE_<LANG>_ARCHIVE_FINISH.

       CMAKE_<LANG>_ARCHIVE_FINISH
	      Rule variable to finish an existing static archive.

	      This is a rule variable that tells CMake how to finish a static archive.	It is used in place of	CMAKE_<LANG>_CREATE_STATIC_LIBRARY
	      on some platforms in order to support large object counts.  See also CMAKE_<LANG>_ARCHIVE_CREATE and CMAKE_<LANG>_ARCHIVE_APPEND.

       CMAKE_<LANG>_COMPILER
	      The full path to the compiler for LANG.

	      This is the command that will be used as the <LANG> compiler. Once set, you can not change this variable.

       CMAKE_<LANG>_COMPILER_ABI
	      An internal variable subject to change.

	      This is used in determining the compiler ABI and is subject to change.

       CMAKE_<LANG>_COMPILER_ID
	      An internal variable subject to change.

	      This is used in determining the compiler and is subject to change.

       CMAKE_<LANG>_COMPILER_LOADED
	      Defined to true if the language is enabled.

	      When language <LANG> is enabled by project() or enable_language() this variable is defined to 1.

       CMAKE_<LANG>_COMPILER_VERSION
	      An internal variable subject to change.

	      Compiler version in major[.minor[.patch[.tweak]]] format.  This variable is reserved for internal use by CMake and is not guaranteed
	      to be set.

       CMAKE_<LANG>_COMPILE_OBJECT
	      Rule variable to compile a single object file.

	      This is a rule variable that tells CMake how to compile a single object file for for the language <LANG>.

       CMAKE_<LANG>_CREATE_SHARED_LIBRARY
	      Rule variable to create a shared library.

	      This is a rule variable that tells CMake how to create a shared library for the language <LANG>.

       CMAKE_<LANG>_CREATE_SHARED_MODULE
	      Rule variable to create a shared module.

	      This is a rule variable that tells CMake how to create a shared library for the language <LANG>.

       CMAKE_<LANG>_CREATE_STATIC_LIBRARY
	      Rule variable to create a static library.

	      This is a rule variable that tells CMake how to create a static library for the language <LANG>.

       CMAKE_<LANG>_FLAGS_DEBUG
	      Flags for Debug build type or configuration.

	      <LANG> flags used when CMAKE_BUILD_TYPE is Debug.

       CMAKE_<LANG>_FLAGS_MINSIZEREL
	      Flags for MinSizeRel build type or configuration.

	      <LANG> flags used when CMAKE_BUILD_TYPE is MinSizeRel.Short for minimum size release.

       CMAKE_<LANG>_FLAGS_RELEASE
	      Flags for Release build type or configuration.

	      <LANG> flags used when CMAKE_BUILD_TYPE is Release

       CMAKE_<LANG>_FLAGS_RELWITHDEBINFO
	      Flags for RelWithDebInfo type or configuration.

	      <LANG> flags used when CMAKE_BUILD_TYPE is RelWithDebInfo. Short for Release With Debug Information.

       CMAKE_<LANG>_IGNORE_EXTENSIONS
	      File extensions that should be ignored by the build.

	      This is a list of file extensions that may be part of a project for a given language but are not compiled.

       CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES
	      Directories implicitly searched by the compiler for header files.

	      CMake does not explicitly specify these directories on compiler command lines for language <LANG>.   This  prevents  system  include
	      directories from being treated as user include directories on some compilers.

       CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES
	      Implicit linker search path detected for language <LANG>.

	      Compilers  typically  pass  directories  containing  language  runtime libraries and default library search paths when they invoke a
	      linker.  These paths are implicit linker search directories for the compiler's language.	CMake automatically detects these directo-
	      ries for each language and reports the results in this variable.

       CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES
	      Implicit link libraries and flags detected for language <LANG>.

	      Compilers  typically  pass  language runtime library names and other flags when they invoke a linker.  These flags are implicit link
	      options for the compiler's language.  CMake automatically detects these libraries and  flags  for  each  language  and  reports  the
	      results in this variable.

       CMAKE_<LANG>_LIBRARY_ARCHITECTURE
	      Target architecture library directory name detected for <lang>.

	      If  the  <lang>  compiler  passes to the linker an architecture-specific system library search directory such as <prefix>/lib/<arch>
	      this variable contains the <arch> name if/as detected by CMake.

       CMAKE_<LANG>_LINKER_PREFERENCE
	      Preference value for linker language selection.

	      The "linker language" for executable, shared library, and module targets is the language whose compiler will invoke the linker.  The
	      LINKER_LANGUAGE  target property sets the language explicitly.  Otherwise, the linker language is that whose linker preference value
	      is highest among languages compiled and linked into the target.  See also the CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES variable.

       CMAKE_<LANG>_LINKER_PREFERENCE_PROPAGATES
	      True if CMAKE_<LANG>_LINKER_PREFERENCE propagates across targets.

	      This is used when CMake selects a linker language for a target.  Languages compiled directly into the target are always  considered.
	      A language compiled into static libraries linked by the target is considered if this variable is true.

       CMAKE_<LANG>_LINK_EXECUTABLE
	      Rule variable to link and executable.

	      Rule variable to link and executable for the given language.

       CMAKE_<LANG>_OUTPUT_EXTENSION
	      Extension for the output of a compile for a single file.

	      This is the extension for an object file for the given <LANG>. For example .obj for C on Windows.

       CMAKE_<LANG>_PLATFORM_ID
	      An internal variable subject to change.

	      This is used in determining the platform and is subject to change.

       CMAKE_<LANG>_SIZEOF_DATA_PTR
	      Size of pointer-to-data types for language <LANG>.

	      This holds the size (in bytes) of pointer-to-data types in the target platform ABI.  It is defined for languages C and CXX (C++).

       CMAKE_<LANG>_SOURCE_FILE_EXTENSIONS
	      Extensions of source files for the given language.

	      This is the list of extensions for a given languages source files.

       CMAKE_COMPILER_IS_GNU<LANG>
	      True if the compiler is GNU.

	      If the selected <LANG> compiler is the GNU compiler then this is TRUE, if not it is FALSE.

       CMAKE_Fortran_MODDIR_DEFAULT
	      Fortran default module output directory.

	      Most  Fortran  compilers write .mod files to the current working directory.  For those that do not, this is set to "." and used when
	      the Fortran_MODULE_DIRECTORY target property is not set.

       CMAKE_Fortran_MODDIR_FLAG
	      Fortran flag for module output directory.

	      This stores the flag needed to pass the value of the Fortran_MODULE_DIRECTORY target property to the compiler.

       CMAKE_Fortran_MODOUT_FLAG
	      Fortran flag to enable module output.

	      Most Fortran compilers write .mod files out by default.  For others, this stores the flag needed to enable module output.

       CMAKE_INTERNAL_PLATFORM_ABI
	      An internal variable subject to change.

	      This is used in determining the compiler ABI and is subject to change.

       CMAKE_USER_MAKE_RULES_OVERRIDE_<LANG>
	      Specify a CMake file that overrides platform information for <LANG>.

	      This is a language-specific version of CMAKE_USER_MAKE_RULES_OVERRIDE loaded only when enabling language <LANG>.
