# find_library is now cc.find_library and now uses the linker to check if a particular library is available (similar to how AC_CHECK_LIB does it). This means you can set the LIBRARY_PATH env variable (when using gcc/clang and the LIBPATH env variable when using MSVC) to point to your "library providing" root. It also accepts a colon-separated list of directories. This is how almost everyone does non-default-linker-search-path library searching and linking.
