Locate SDL_ttf library
This module defines:
SDL_TTF_LIBRARIES, the name of the library to link against SDL_TTF_INCLUDE_DIRS, where to find the headers SDL_TTF_FOUND, if false, do not try to link against SDL_TTF_VERSION_STRING - human-readable string containing the version of SDL_ttf
For backward compatibility the following variables are also set:
SDLTTF_LIBRARY (same value as SDL_TTF_LIBRARIES) SDLTTF_INCLUDE_DIR (same value as SDL_TTF_INCLUDE_DIRS) SDLTTF_FOUND (same value as SDL_TTF_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).
