PR accellera-official#347 allows custom SystemC library directories by adding all ${SYSTEMC_HOME}/lib* directories to the search path. When multiple variants exist, prefer ${SYSTEMC_HOME}/${CMAKE_INSTALL_LIBDIR} first. While CCI and SystemC may use different install settings, this is our best available guess and avoids relying on glob order when both use the same configuration. The existing lib* search remains as fallback.

find_package(SystemCLanguage) from CCI happens in configuration/CMakeLists.txt (sub-directory) which only hardcodes /opt/systemc this will make cmake look into /opt/systemc/lib/cmake/SystemCLanguage and /opt/systemc/lib64/cmake/SystemCLanguage
It would be nice if cmake would discover SystemC installations by SYSTEMC_HOME. In addition it should still discover it, if custom CMAKE_INSTALL_LIBDIR was used which is not /lib or /lib64. (e.g. linux64 ...)
The code therefore adds $SYSTEMC_HOME to CMAKE_PREFIX_PATH and the underlying lib dirs
I'm not a cmake specialist but I'm currently working on cmake for SystemC AMS were needed it as well, feedback is welcome.
