In the current implementation, library suffixes are hard coded from a hand-maintained list. Instead of writing this list, we can use the CMake macros for platform specific library prefix/suffixes. E.g. https://cmake.org/cmake/help/v3.0/variable/CMAKE_STATIC_LIBRARY_SUFFIX.html This also resolves library resolution on Mac OSX, which does not currently work on the native `.dylib` suffix for shared libraries.
