As nf-config does not provide an equivalent --libdir output we must derive the info ourselves. --flibs provided the info previously, but it may be more practical to use the --prefix output and search suspected suffixes instead as --flibs contains other libraries' link info. To handle the cases where --prefix is empty, we still fall back to --flibs and if that proves insufficient then the as a last resort one directory above the include directory can be used as a substitute for the prefix.

DESCRIPTION OF CHANGES:
Problem:
As nf-config does not provide an equivalent --libdir output we must derive the info ourselves. --flibs provided the info previously, but it may be more practical to use the --prefix output and search suspected suffixes instead as --flibs contains other libraries' link info.
Solution:
Use output of --prefix from nf-config as the primary source of library dir. To handle the cases where --prefix is empty, we still fall back to --flibs and if that proves insufficient then the as a last resort one directory above the include directory can be used as a substitute for the prefix.
TESTS CONDUCTED:
RELEASE NOTE: Better nf-config libdir detection in CMake build
