# FindSDL2_image |
|
# ------------- |
|
# |
|
# Locate SDL2_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 SDL2_image |
|
# |
|
# |
|
# |
|
# For backward compatibility the following variables are also set: |
|
# |
|
# :: |
|
# |
|
# SDL2IMAGE_LIBRARY (same value as SDL2_IMAGE_LIBRARIES) |
|
# SDL2IMAGE_INCLUDE_DIR (same value as SDL2_IMAGE_INCLUDE_DIRS) |
|
# SDL2IMAGE_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). |
