# Locate OpenGL
# This module defines:
# 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
# OPENGL_gl_LIBRARY - Path to OpenGL Library
# OPENGL_glu_LIBRARY - Path to GLU Library
# The implementation is based on the standard FindOpenGL.cmake provided with CMake,
# but customized for targeting Emscripten only.
# These libraries are provided with Emscripten
