| # Locate SDL2 library | ||
| # This module defines | ||
| # SDL2_LIBRARY, the name of the library to link against | ||
| # SDL2_FOUND, if false, do not try to link to SDL2 | ||
| # SDL2_INCLUDE_DIR, where to find SDL.h | ||
| # | ||
| # This module responds to the the flag: | ||
| # SDL2_BUILDING_LIBRARY | ||
| # If this is defined, then no SDL2_main will be linked in because | ||
| # only applications need main(). | ||
| # Otherwise, it is assumed you are building an application and this | ||
| # module will attempt to locate and set the the proper link flags | ||
| # as part of the returned SDL2_LIBRARY variable. | ||
| # | ||
| # Don't forget to include SDL2main.h and SDL2main.m your project for the | ||
| # OS X framework based version. (Other versions link to -lSDL2main which | ||
| # this module will try to find on your behalf.) Also for OS X, this | ||
| # module will automatically add the -framework Cocoa on your behalf. | ||
| # | ||
| # | ||
| # Additional Note: If you see an empty SDL2_LIBRARY_TEMP in your configuration | ||
| # and no SDL2_LIBRARY, it means CMake did not find your SDL2 library | ||
| # (SDL2.dll, libsdl2.so, SDL2.framework, etc). | ||
| # Set SDL2_LIBRARY_TEMP to point to your SDL2 library, and configure again. | ||
| # Similarly, if you see an empty SDL2MAIN_LIBRARY, you should set this value | ||
| # as appropriate. These values are used to generate the final SDL2_LIBRARY | ||
| # variable, but when these values are unset, SDL2_LIBRARY does not get created. | ||
| # | ||
| # | ||
| # $SDL2 is an environment variable that would | ||
| # correspond to the ./configure --prefix=$SDL2 | ||
| # used in building SDL2. | ||
| # l.e.galup 9-20-02 | ||
| # | ||
| # Modified by Eric Wing. | ||
| # Added code to assist with automated building by using environmental variables | ||
| # and providing a more controlled/consistent search behavior. | ||
| # Added new modifications to recognize OS X frameworks and | ||
| # additional Unix paths (FreeBSD, etc). | ||
| # Also corrected the header search path to follow "proper" SDL2 guidelines. | ||
| # Added a search for SDL2main which is needed by some platforms. | ||
| # Added a search for threads which is needed by some platforms. | ||
| # Added needed compile switches for MinGW. | ||
| # | ||
| # On OSX, this will prefer the Framework version (if found) over others. | ||
| # People will have to manually change the cache values of | ||
| # SDL2_LIBRARY to override this selection or set the CMake environment | ||
| # CMAKE_INCLUDE_PATH to modify the search paths. | ||
| # | ||
| # Note that the header path has changed from SDL2/SDL.h to just SDL.h | ||
| # This needed to change because "proper" SDL2 convention | ||
| # is #include "SDL.h", not <SDL2/SDL.h>. This is done for portability | ||
| # reasons because not all systems place things in SDL2/ (see FreeBSD). | ||
| # | ||
| # Ported by Johnny Patterson. This is a literal port for SDL2 of the FindSDL.cmake | ||
| # module with the minor edit of changing "SDL" to "SDL2" where necessary. This | ||
| # was not created for redistribution, and exists temporarily pending official | ||
| # SDL2 CMake modules. | ||
| # | ||
| # Note that on windows this will only search for the 32bit libraries, to search | ||
| # for 64bit change x86/i686-w64 to x64/x86_64-w64 | ||
