# 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.

# In addition, OpenAL is open source, and it is possible to compile on Panther.

# transition to OpenAL 1.1, it is common to need to override the built-in

2007-12-21 04:59:44 +03:00
