# - 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 - 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
