Conditions/suggestions to use shared library in C/C++ coding

What are the basic conditions to use other people's library in C/C++ coding?
Here I do not mean the compiling step, but at the step of writing source code (from scratch in a way!).
When using Standard C/C++ Library normally the header (.h/hpp) and corresponding implementation (.c/.cpp) files are included in the source code, then the multiple files are compiled.
I could not find a good tutorial/textbook on how to use other people's libraries except this one so far.
For example, gzlib is quite commonly used to handle compressed files, but I am blank how to use it in my own code. Also when people says libXYZ is needed for his code I become lost too. I think I understand "a 'library' is a collection of compiled functions and class declarations". So, my question is:
What is the general condition (suggestions) to use an non-standard library from a third party?
At this moment, I restrict my question to GCC/G++ in GNU-Linux or Unix-based CLI, not any GUI tools or other GUI-based IDE etc.

Thanks a lot!

raptor-config(1)					      General Commands Manual						  raptor-config(1)

NAME
raptor-config - script to get information about the installed version of Raptor SYNOPSIS
raptor-config [--cflags] [--options] [--help] [--libs] [--libtool-libs] [--private-libs] [--prefix[=DIR]] [--version-decimal] [--version] DESCRIPTION
raptor-config is a tool that is used to determine the compile and linker flags that should be used to compile and link programs that use the Raptor RDF parser library. OPTIONS
raptor-config accepts the following options: --cflags Print the compiler flags that are necessary to compile a raptor program. --options Print raptor compiled options such as parsers and serializers available, the XML parser used (if any) and the WWW retrieval library used (if any). --help Print a help message summarising usage. --libs Print the linker flags that are necessary to link a raptor program. This excludes linker arguments used to build the raptor shared library. --libtool-libs Print the path to the libtool file for raptor. --private-libs Print the linker flags that are necessary to build the raptor shared library. This option is not usually needed because the raptor shared library has already been dynamically linked against these flags. --prefix=PREFIX If specified, use PREFIX instead of the installation prefix that raptor was built with when computing the output for the --cflags and --libs options. This option must be specified before any --libs or --cflags options. --version Print the currently installed version of raptor on the standard output. --version-decimal Print the currently installed version of raptor as a decimal integer.
