FindOpenAL
|
||
|
|
----------
|
||
|
|
|
||
|
|
|
||
|
|
Finds Open Audio Library (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.
