# FindOpenGL
|
|
# ----------
|
|
#
|
|
# FindModule for OpenGL and 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.
