FindGLUI.cmake

# - Try to find GLUI (GL User Interface)
# Requires OpenGL and GLUT - searches for them using find_package
# Once done, this will define
#
#	GLUI_INCLUDE_DIR, where to find GL/glui.h (or GLUI/glui.h on mac)
#	GLUI_LIBRARY, the libraries to link against
#	GLUI_FOUND, If false, do not try to use GLUI.
#
# Plural versions refer to this library and its dependencies, and
# are recommended to be used instead, unless you have a good reason.
#
# Useful configuration variables you might want to add to your cache:
#   GLUI_ROOT_DIR - A directory prefix to search
#                  (usually a path that contains include/ as a subdirectory)
