I was hoping we could do this. But the problem seems to be as follows:

1)In FindOpenGL.cmake OPENGL_XMESA_FOUND is set to True if OPENGL_xmesa_INCLUDE_DIR is True

    FIND_PATH(OPENGL_xmesa_INCLUDE_DIR GL/xmesa.h
      /usr/share/doc/NVIDIA_GLX-1.0/include
      /usr/openwin/share/include
      /opt/graphics/OpenGL/include /usr/X11R6/include
    )

Here GL/xmesa.h  seems to be the problem. The "XMesa" interface is deprecated and GL/xmesa*.h files are  no longer considered public.
