1# - Locate OpenAL
2# This module defines
3#  OPENAL_LIBRARY
4#  OPENAL_FOUND, if false, do not try to link to OpenAL
5#  OPENAL_INCLUDE_DIR, where to find the headers
6#
7# $OPENALDIR is an environment variable that would
8# correspond to the ./configure --prefix=$OPENALDIR
9# used in building OpenAL.

18# Created by Eric Wing. This was influenced by the FindSDL.cmake module.
19# On OSX, this will prefer the Framework version (if found) over others.
20# People will have to manually change the cache values of
21# OPENAL_LIBRARY to override this selection.
22# Tiger will include OpenAL as part of the System.
23# But for now, we have to look around.
24# Other (Unix) systems should be able to utilize the non-framework paths.
