Subject: [PATCH] Fix configuration with Emscripten
In Emscripten there is no separate libm library, so there is no need to explicitly link it,
and in particular the find_library call would fail as there is not libm to find.
See https://stackoverflow.com/questions/24663915/how-can-i-link-libm-to-my-emscripten-port
