#[=======================================================================[.rst:
FindSDL_gfx
-------------
-----------
Locate SDL_gfx library
@ -11,36 +11,19 @@ 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
For backward compatibility the following variables are also set:
::
SDLGFX_LIBRARY (same value as SDL_GFX_LIBRARIES)
SDLGFX_INCLUDE_DIR (same value as SDL_GFX_INCLUDE_DIRS)
SDLGFX_FOUND (same value as SDL_GFX_FOUND)
$SDLDIR is an environment variable that would correspond to the
./configure --prefix=$SDLDIR used in building SDL.
Created by Xavier Del Campo, heavily based on the original work by
Eric Wing, FindSDL_mixer.cmake.
