# FindSDL2_ttf
# -------------
#
# Locate SDL2_ttf library
#
# This module defines:
#
# ::
#
# SDL2_TTF_LIBRARIES, the name of the library to link against
# SDL2_TTF_INCLUDE_DIRS, where to find the headers
# SDL2_TTF_FOUND, if false, do not try to link against
# SDL2_TTF_VERSION_STRING - human-readable string containing the
# version of SDL2_ttf
#
#
#
# For backward compatibility the following variables are also set:
#
# ::
#
# SDL2TTF_LIBRARY (same value as SDL2_TTF_LIBRARIES)
# SDL2TTF_INCLUDE_DIR (same value as SDL2_TTF_INCLUDE_DIRS)
# SDL2TTF_FOUND (same value as SDL2_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).
