[Cmake] CMake OpenGL include on OS X

[Andy Cedilnik]

Hi Chris,

I think you should have check in your code:

#if defined(PROJECT_USE_X) || defined(_WIN32)
# include <GL/gl.h>
#else
# include <OpenGL/gl.h>
#endif

I'm using the Aqua implementation, so I want to make sure that I'm using headers from the OpenGL framework. I'm including <OpenGL/gl.h> rather than <GL/gl.h>, but I don't want to accidentally grab a header from X11. Here are the lines from my CMakeCache.txt:
