# FindOpenAL
|
||||
# ----------
|
||||
#
|
||||
#
|
||||
#
|
||||
# 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.
|
||||
|
||||
# This makes the presumption that you are include al.h like
|
||||
# #include "al.h"
|
||||
# and not
|
||||
# #include <AL/al.h>
|
||||
# The reason for this is that the latter is not entirely portable.
|
||||
# Windows/Creative Labs does not by default put their headers in AL/ and
|
||||
# OS X uses the convention <OpenAL/al.h>.
|
||||
#
|
||||
# For Windows, Creative Labs seems to have added a registry key for their
|
||||
# OpenAL 1.1 installer. I have added that key to the list of search paths,
|
||||
# however, the key looks like it could be a little fragile depending on
|
||||
# if they decide to change the 1.00.0000 number for bug fix releases.
|
||||
# Also, they seem to have laid down groundwork for multiple library platforms
|
||||
# which puts the library in an extra subdirectory. Currently there is only
|
||||
# Win32 and I have hardcoded that here. This may need to be adjusted as
|
||||
# platforms are introduced.
|
||||
# The OpenAL 1.0 installer doesn't seem to have a useful key I can use.
|
||||
# I do not know if the Nvidia OpenAL SDK has a registry key.
|
||||
#
|
||||
# For OS X, remember that OpenAL was added by Apple in 10.4 (Tiger).
|
||||
# To support the framework, I originally wrote special framework detection
|
||||
# code in this module which I have now removed with CMake's introduction
|
||||
# of native support for frameworks.
|
||||
# In addition, OpenAL is open source, and it is possible to compile on Panther.
|
||||
# Furthermore, due to bugs in the initial OpenAL release, and the
|
||||
# transition to OpenAL 1.1, it is common to need to override the built-in
|
||||
# framework.
|
||||
# Per my request, CMake should search for frameworks first in
|
||||
# the following order:
|
||||
# ~/Library/Frameworks/OpenAL.framework/Headers
|
||||
# /Library/Frameworks/OpenAL.framework/Headers
|
||||
# /System/Library/Frameworks/OpenAL.framework/Headers
|
||||
#
|
||||
# On OS X, 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 or set the CMake environment
|
||||
# CMAKE_INCLUDE_PATH to modify the search paths.
