FindSFML.cmake: Ignored environment variables to find library paths

Browse Source 
Environment variables (e.g. PATH on Windows) are looked up early by CMake, and libraries found there are prioritized over those in SFML's own folder. To avoid paths to wrong libraries, this commit modifies the CMake find_library() call, such that environment variables are no longer considered as suitable paths.
