# 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).
|
|
|
|
# On OSX, this will prefer the Framework version (if found) over others.
|
|
# People will have to manually change the cache values of
|
|
# SDLIMAGE_LIBRARY to override this selection.
