Title: explicitly link against gl libraries

Cogl does not explicitly link against GL or GLES any more, and Clutter master dropped the 'gl' pkg-config requirement because it introduced unneeded and conflicting dependencies.

Cinnamon still uses glXQuery* API, so it needs to explicitly link against libGL.
