1# - Locate FreeAlut
2# This module defines
3#  ALUT_LIBRARY
4#  ALUT_FOUND, if false, do not try to link against Alut
5#  ALUT_INCLUDE_DIR, where to find the headers
6#
7# $ALUTDIR is an environment variable that would
8# correspond to the ./configure --prefix=$ALUTDIR
9# used in building Alut.
10#
11# Created by Eric Wing. This was influenced by the FindSDL.cmake module.
12# On OSX, this will prefer the Framework version (if found) over others.
13# People will have to manually change the cache values of
14# ALUT_LIBRARY to override this selection.
15# Tiger will include OpenAL as part of the System.
16# But for now, we have to look around.
17# Other (Unix) systems should be able to utilize the non-framework paths.
18#
19# Several changes and additions by Fabian 'x3n' Landau
20# Some simplifications by Adrian Friedli and Reto Grieder
