# - Try to find OpenGL
# 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_GL - the GL include directory
# OPENGL_INCLUDE_DIR_GLX - the GLX 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
#
# Define controlling option OPENGL_USE_AQUA if on Apple -
# if this is not true, look for the X11 OpenGL. Defaults
# to true.
