Locate SDL_gfx library
This module defines:
::
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.
