[Cogl] Error when compiling with mingw-w64

[Neil Roberts]

Hi,

I think the problem may be with how you've named the gl header. The name
OpenGL/gl.h is only used on OS X whereas everywhere else calls it
GL/gl.h. It looks like if the configure script finds OpenGL/gl.h it will
enable the quartz platform and that stops it from enabling WGL.

So I guess you just need to rename the GL header to GL/gl.h and then
when you rerun configure verify that it has the following lines at the
end:

• Features:
        Drivers:  gl
        GL Window System APIs: wgl

Hope that helps.

Regards,
- Neil
