FindSDL_gfx
|
|
-------------
|
|
|
|
Locate SDL_gfx library
|
|
|
|
This module defines:
|
|
|
|
::
|
|
|
|
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.
