# FindGLUT
# --------
#
# try to find glut library and include files.
#
# IMPORTED Targets
# ^^^^^^^^^^^^^^^^
#
# This module defines the :prop_tgt:`IMPORTED` targets:
#
# ``GLUT::GLUT``
#  Defined if the system has GLUT.
#
# Result Variables
# ^^^^^^^^^^^^^^^^
#
# This module sets the following variables:
#
# ::
#
#   GLUT_INCLUDE_DIR, where to find GL/glut.h, etc.
#   GLUT_LIBRARIES, the libraries to link against
#   GLUT_FOUND, If false, do not try to use GLUT.
#
# Also defined, but not for general use are:
#
# ::
#
#   GLUT_glut_LIBRARY = the full path to the glut library.
#   GLUT_Xmu_LIBRARY  = the full path to the Xmu library.
#   GLUT_Xi_LIBRARY   = the full path to the Xi Library.
