Embedding Runtime Search Path into Library on AIX

My product has 2 libraries say "x & y".
x depends on y.

During the installation of my products package, user will be prompted for his own location to copy my product libraries.
Installation will copy libraries "x & y" and create my product specific ENV variable say "MYPATH" pointing to User picked install location.

Here User doesn't want to set LIBPATH nor he want to create any softlinks in "/usr/lib or /lib".

Now I should make my library "x" find its dependent "y" in the environment where there is no LIBPATH set nor softlinks created in "/usr/lib or /lib".

On other UNIX platforms, there is a concept of $ORIGIN and i am successful using this on other Unix platforms.

Since there is no concept of $ORIGIN on AIX, trying out alternatives on AIX

My Scenario:
************

My package install creates ENV variable “MYPATH” pointing to the User picked installed location.
Let say, User selected /home/lib and install will set "MYPATH=/home/lib"

Now I thought of accessing this variable in the runtime search path (Either specifying using -L or –blibpath) while building my libraries (x & y).

For a particular library, runtime search path(dump -X32 -H) should be like
INDEX PATH
0 $MYPATH

I’ve tried specifying $MYPATH in the makefile using “-L or –blibpath” but as MYPATH is not available during build time, NULL value got replaced.

INDEX PATH
0

I want $MYPATH to be considered as is so that at runtime it gets replaced with its value.

Tried Escaping $ and also used quotes but no use.
ex: $$$MYPATH$

Can this be possible? If possible, then how?

mh_installjar

MAVEN(1)							   User Commands							  MAVEN(1)

NAME

       Maven - Installs a jar into /usr/share/maven-repo.

SYNOPSIS

       mh_installjar [option]... [pom] [jar] [link]...

DESCRIPTION

       Installs the jar file in /usr/share/maven-repo, at the correct location for Maven. The jar is copied into the build directory.  It can also
       create additional links to the jar, usually located in /usr/share/java.

       Where

	      [pom] is the location of the POM associated with the jar to install.

	      GroupId, artifactId and version will be extracted from this file.

	      [jar] is the path to the jar to install, usually located in the build

	      folder.

	      [link] is an additional link to the jar to install, usually there should

	      be a link to usr/share/java/$jar.jar and usr/share/java/$jar-$version.jar to comply with the Java packaging  guidelines.	Note  that
	      there is no need to specify those particular links if the --java-lib option is used.

OPTIONS

       -h --help: show this text

       -V --version: show the version

       -p<package> --package=<package>: name of the Debian package which

	      will contain this jar file

       -e<version>, --set-version=<version>: set the version for the jar,

	      do not use the version declared in the POM file.

       -r<rules> --rules=<rules>: path to the file containing the

	      rules to apply when cleaning the POM.  Optional, the default location is debian/maven.rules Maven rules are used here to extract the
	      groupId, artifactId and version from the POM file.

       -l --java-lib: Optional, if given it will install the jar into

	      /usr/share/java to comply with the Debian Java specification.  The jar will be installed as /usr/share/java/$name-$version.jar and a
	      versionless link /usr/share/java/$name.jar will point to it, as well as the links installed in /usr/share/maven-repo

       -n<name> --usj-name=<name>: Optional, the name to use when installing the

	      library in /usr/share/java when --java-lib is used.  Defaults to the artifact id found in the POM.

       -j<version> --usj-version=<version>: Optional, the version to use when

	      installing the library in /usr/share/java when --java-lib is used.  Defaults to the version found in the POM.

       -s --no-usj-versionless: Optional, don't install the versionless link

	      in /usr/share/java.  This flag is used only when the -l or --java-lib option is given.

       -d<path> --dest-jar=<path>: Optional, the destination for the real jar.

	      The  other  places  where  the  jar  appears,  in the repository or in the list of links, will be symlinks to this jar.  Defaults to
	      /usr/share/java/$name-$version.jar if --java-lib is used, otherwise the jar is installed in the versioned path in the Maven  reposi-
	      tory.

       -c<classifier> --classifier=<classifier>: Optional, the classifier for

	      the jar. Empty by default.

       -v --verbose: show more information while running

       -n --no-act: don't actually do anything, just print the results

       --skip-clean-pom: don't clean the pom, assume that a previous action ran

	      mh_cleanpom with the correct options. mh_cleanpom is run only to extract the groupId, artifactId and version of the jar
