Martin Gräßlin 03231942bb Bind building of glx support on whether epoxy has a glx header ... So far it was bound to whether we build for GLES. But this is semantically wrong. It might be possible that even on desktop gl epoxy is built without GLX support, thus we need to reflect this. This change ensures that epoxy/glx.h is only included if available, that relevant code is bound to it and that checks are in place to enforce EGL if not build with glx support. In addtion the glxbackend.cpp is now only included in the build set if available.		2015-11-03 09:29:31 +01:00
