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). |
