| # - Locate SDL2 library (modified from CMake's FindSDL.cmake) | ||
| # This module defines | ||
| # SDL2_LIBRARY, the name of the library to link against | ||
| # SDL2_FOUND, if false, do not try to link to SDL | ||
| # SDL2_INCLUDE_DIR, where to find SDL.h | ||
| # SDL2_VERSION_STRING, human-readable string containing the version of SDL2 | ||
| # | ||
| # This module responds to the the flag: | ||
| # SDL2_BUILDING_LIBRARY | ||
| # If this is defined, then no SDL_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. | ||
| # | ||
| # 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. | ||
| # | ||
| # | ||
| # $SDLDIR is an environment variable that would | ||
| # correspond to the ./configure --prefix=$SDLDIR | ||
| # used in building SDL. | ||
