# - Locates the SDL_sound library
|
||||
#
|
||||
# This module depends on SDL being found and
|
||||
# must be called AFTER FindSDL.cmake is called.
|
||||
#
|
||||
# This module defines
|
||||
# SDL_SOUND_INCLUDE_DIR, where to find SDL_sound.h
|
||||
# SDL_SOUND_FOUND, if false, do not try to link to SDL_sound
|
||||
# SDL_SOUND_LIBRARIES, this contains the list of libraries that you need
|
||||
# to link against. This is a read-only variable and is marked INTERNAL.
|
||||
# SDL_SOUND_EXTRAS, this is an optional variable for you to add your own
|
||||
# flags to SDL_SOUND_LIBRARIES. This is prepended to SDL_SOUND_LIBRARIES.
|
||||
# This is available mostly for cases this module failed to anticipate for
|
||||
# and you must add additional flags. This is marked as ADVANCED.
|
||||
# SDL_SOUND_VERSION_STRING, human-readable string containing the version of SDL_sound
|
||||
#
|
||||
# This module also defines (but you shouldn't need to use directly)
|
||||
# SDL_SOUND_LIBRARY, the name of just the SDL_sound library you would link
|
||||
# against. Use SDL_SOUND_LIBRARIES for you link instructions and not this one.
|
||||
# And might define the following as needed
|
||||
# MIKMOD_LIBRARY
|
||||
# MODPLUG_LIBRARY
|
||||
# OGG_LIBRARY
|
||||
# VORBIS_LIBRARY
|
||||
# SMPEG_LIBRARY
|
||||
# FLAC_LIBRARY
|
||||
# SPEEX_LIBRARY
|
||||
#
|
||||
# Typically, you should not use these variables directly, and you should use
|
||||
# SDL_SOUND_LIBRARIES which contains SDL_SOUND_LIBRARY and the other audio libraries
|
||||
# (if needed) to successfully compile on your system.
|
||||
#
|
||||
# Created by Eric Wing.
|
||||
# This module is a bit more complicated than the other FindSDL* family modules.
|
||||
# The reason is that SDL_sound can be compiled in a large variety of different ways
|
||||
# which are independent of platform. SDL_sound may dynamically link against other 3rd
|
||||
# party libraries to get additional codec support, such as Ogg Vorbis, SMPEG, ModPlug,
|
||||
# MikMod, FLAC, Speex, and potentially others.
|
||||
# Under some circumstances which I don't fully understand,
|
||||
# there seems to be a requirement
|
||||
# that dependent libraries of libraries you use must also be explicitly
|
||||
# linked against in order to successfully compile. SDL_sound does not currently
|
||||
# have any system in place to know how it was compiled.
|
||||
# So this CMake module does the hard work in trying to discover which 3rd party
|
||||
# libraries are required for building (if any).
|
||||
# This module uses a brute force approach to create a test program that uses SDL_sound,
|
||||
# and then tries to build it. If the build fails, it parses the error output for
|
||||
# known symbol names to figure out which libraries are needed.
|
||||
#
|
||||
# Responds to the $SDLDIR and $SDLSOUNDDIR environmental variable that would
|
||||
# correspond to the ./configure --prefix=$SDLDIR used in building SDL.
|
||||
#
|
||||
# On OSX, this will prefer the Framework version (if found) over others.
|
||||
# People will have to manually change the cache values of
|
||||
# SDL_LIBRARY to override this selectionor set the CMake environment
|
||||
# CMAKE_INCLUDE_PATH to modify the search paths.
