[CMake] Linking OpenGL in Win32

[Olivier Delannoy]

GLFW 3.0 is under development and has migrate its built process to
CMake. You can find a correct use of FindOPENGL and a concrete CMake
built process which build OpenGL application. The build process is
relatively small so you should be able to find your answer easily
looking at the project source
http://sourceforge.net/projects/glfw.
It's in the CVS source browser BRANCH_3_0.
I hope it will help you figures what's wrong with your build process.
