Revert "cmake: Allow to specify glext headers include path."

I ran into build failures due to missing GL_UNSIGNED_INT_2_10_10_10_REV
symbol, but it was caused by old glew headers, not old glext headers.
So take this back until it actually makes a difference.

This reverts commit 838c703bb9be6d89a226f2239dbb44c85d53da57.
