FindSDL_image
|
|
-------------
|
|
|
|
Locate SDL_image library
|
|
|
|
This module defines:
|
|
|
|
::
|
|
|
|
SDL_IMAGE_LIBRARIES, the name of the library to link against
|
|
SDL_IMAGE_INCLUDE_DIRS, where to find the headers
|
|
SDL_IMAGE_FOUND, if false, do not try to link against
|
|
SDL_IMAGE_VERSION_STRING - human-readable string containing the
|
|
version of SDL_image
|
|
|
|
|
|
|
|
For backward compatibility the following variables are also set:
|
|
|
|
::
|
|
|
|
SDLIMAGE_LIBRARY (same value as SDL_IMAGE_LIBRARIES)
|
|
SDLIMAGE_INCLUDE_DIR (same value as SDL_IMAGE_INCLUDE_DIRS)
|
|
SDLIMAGE_FOUND (same value as SDL_IMAGE_FOUND)
|
|
|
|
|
|
|
|
$SDLDIR is an environment variable that would correspond to the
|
|
./configure --prefix=$SDLDIR used in building SDL.
