# FindGLUT - Find GLUT library
# This module finds if GLUT is installed and determines where the include
# files and libraries are.

# This module defines the following variables:
# GLUT_FOUND, if false, do not try to link to GLUT
# GLUT_INCLUDE_DIRS, where to find the headers
# GLUT_LIBRARIES, the libraries to link against
