+# Locate the SDL2_image library. This CMake module is a modified version
+# of the original FindSDL_image.cmake file

+# Locate SDL_image library
+# This module defines
+# SDL2IMAGE_LIBRARY, the name of the library to link against
+# SDLIMAGE_FOUND, if false, do not try to link to SDL
+# SDL2IMAGE_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).
