FindModule for OpenGL and GLU.

## IMPORTED Targets

This module defines the `IMPORTED` targets:

`OpenGL::GL`
  Defined if the system has OpenGL.
`OpenGL::GLU`
  Defined if the system has GLU.

## Result Variables

This module sets the following variables:

`OPENGL_FOUND`
  True, if the system has OpenGL.
`OPENGL_XMESA_FOUND`
  True, if the system has XMESA.
`OPENGL_GLU_FOUND`
  True, if the system has GLU.
`OPENGL_INCLUDE_DIR`
  Path to the OpenGL include directory.
`OPENGL_LIBRARIES`
  Paths to the OpenGL and GLU libraries.

If you want to use just GL you can use these values:

`OPENGL_gl_LIBRARY`
  Path to the OpenGL library.
`OPENGL_glu_LIBRARY`
  Path to the GLU library.

## OSX Specific

On OSX default to using the framework version of OpenGL. People will have to change the cache values of OPENGL_glu_LIBRARY and OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX.
