FindSDL_image
: Locate SDL_image library This module defines SDLIMAGE_LIBRARY, the name of the library to link against SDLIMAGE_FOUND, if false, do not try to link to SDL SDLIMAGE_INCLUDE_DIR, where to find SDL/SDL.h
$SDLDIR is an environment variable that would correspond to the ./configure --prefix=$SDLDIR used in building SDL.
Created by Eric Wing. This was influenced by the FindSDL.cmake module, but with modifications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc).
