|
|
|
|
|
::
|
|
|
|
|
|
|
|
|
|
SDL::SDL_gfx, the name of the target to use with target_*() commands
|
|
|
|
|
SDL_GFX_LIBRARIES, the name of the library to link against
|
|
|
|
|
SDL_GFX_INCLUDE_DIRS, where to find the headers
|
|
|
|
|
SDL_GFX_FOUND, if false, do not try to link against
|
|
|
|
|
SDL_GFX_VERSION_STRING - human-readable string containing the
|
|
|
|
|
version of SDL_gfx
|
|
|
|
|
|
|
|
|
|
``$SDLDIR`` is an environment variable that would correspond to the
|
|
|
|
|
``./configure --prefix=$SDLDIR`` used in building SDL.
