# Once done this will define
#
# OPENGL_FOUND - system has OpenGL
# OPENGL_XMESA_FOUND - system has XMESA
# OPENGL_GLU_FOUND - system has GLU
# OPENGL_INCLUDE_DIR - the GL include directory
# OPENGL_LIBRARIES - Link these to use OpenGL and GLU
#
# If you want to use just GL you can use these values
# OPENGL_gl_LIBRARY - Path to OpenGL Library
# OPENGL_glu_LIBRARY - Path to GLU Library
#
# 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
