-# Locate SDL_image library
-#
-# This module defines:
-#
-# ::
-#
-# SDL2_IMAGE_LIBRARIES, the name of the library to link against
-# SDL2_IMAGE_INCLUDE_DIRS, where to find the headers
-# SDL2_IMAGE_FOUND, if false, do not try to link against
-# SDL2_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 SDL2_IMAGE_LIBRARIES)
-# SDLIMAGE_INCLUDE_DIR (same value as SDL2_IMAGE_INCLUDE_DIRS)
-# SDLIMAGE_FOUND (same value as SDL2_IMAGE_FOUND)
-#
-#
-#
-# $SDLDIR is an environment variable that would correspond to the
-# ./configure --prefix=$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).
