1 # - Locate SDL_image library
2 # This module defines:
3 # SDL2_IMAGE_LIBRARIES, the name of the library to link against
4 # SDL2_IMAGE_INCLUDE_DIRS, where to find the headers
5 # SDL2_IMAGE_FOUND, if false, do not try to link against
6 # SDL2_IMAGE_VERSION_STRING - human-readable string containing the version of SDL_image
7 #
8 # $SDLDIR is an environment variable that would
9 # correspond to the ./configure --prefix=$SDLDIR
10 # used in building SDL.
11 #
12 # Created by Eric Wing. This was influenced by the FindSDL.cmake
13 # module, but with modifications to recognize OS X frameworks and
14 # additional Unix paths (FreeBSD, etc).
