FindSDL_sound
|
|
-------------
|
|
|
|
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.
|
|
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.

# CMake is giving me problems using TRY_COMPILE with the CMAKE_FLAGS
|
|
# for the :STRING syntax if I have multiple values contained in a
|
|
# single variable. This is a problem for the SDL_LIBRARY variable
|
|
# because it does just that. When I feed this variable to the command,
|
|
# only the first value gets the appropriate modifier (e.g. -I) and
|
|
# the rest get dropped.
|
|
# To get multiple single variables to work, I must separate them with a "\;"
|
|
# I could go back and modify the FindSDL.cmake module, but that's kind of painful.
|
|
# The solution would be to try something like:
|
|
# string(APPEND SDL_TRY_COMPILE_LIBRARY_LIST "\;${CMAKE_THREAD_LIBS_INIT}")
|
|
# Instead, it was suggested on the mailing list to write a temporary CMakeLists.txt
|
|
# with a temporary test project and invoke that with TRY_COMPILE.
