Summary

0003371: Using X with GL and APPLE

Description

Building on APPLE with VTK_USE_X requires that the user manually set OPENGL_gl_LIBRARY, OPENGL_glu_LIBRARY, and OPENGL_INCLUDE_DIR.

This tidbit of inforrmation is burried in the comment at the top of ${CMAKE_ROOT}/Modules/FindOpenGL.cmake. The build goes OK for quite awhile until the Rendering directory starts building, and then the compiler can not find "GL/gl.h" and it breaks.

The following patch makes CMAKE issue an error if these variables are not set. This let's the end user know upfront what the problem is and how to fix it.
