# Locate OpenAL

|
|
# This module defines
|
||
|
|
# OPENAL_LIBRARY
|
||
|
|
# OPENAL_FOUND, if false, do not try to link to OpenAL
|
||
|
|
# OPENAL_INCLUDE_DIR, where to find the headers
|
||
|
|
#
|
||
|
|
# $OPENALDIR is an environment variable that would
|
||
|
|
# correspond to the ./configure --prefix=$OPENALDIR
|
||
|
|
# used in building OpenAL.

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