1# Locate SDL_image library
2#
3# This module defines:
4#
5# ::
6#
7#   SDL_TTF_LIBRARIES, the name of the library to link against
8#   SDL_TTF_INCLUDE_DIRS, where to find the headers
9#   SDL_TTF_FOUND, if false, do not try to link against
10#   SDL_F_VERSION_STRING - human-readable string containing the version of SDL_ttf
11#
12#
13#
14# For backward compatiblity the following variables are also set:
15#
16# ::
17#
18#   SDLTTF_LIBRARY (same value as SDL_TTF_LIBRARIES)
19#   SDLTTF_INCLUDE_DIR (same value as SDL_TTF_INCLUDE_DIRS)
20#   SDLTTF_FOUND (same value as SDL_TTF_FOUND)
21#
22#
23#
24# $SDLDIR is an environment variable that would correspond to the
25# ./configure --prefix=$SDLDIR used in building SDL.
26#
27# Created by Eric Wing.  This was influenced by the FindSDL.cmake
28# module, but with modifications to recognize OS X frameworks and
29# additional Unix paths (FreeBSD, etc).
