#.rst:
# 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
#
# $SDL2DIR is an environment variable that would correspond to the
# ./configure --prefix=$SDL2DIR used in building SDL.
#
# Created by Eric Wing. This was influenced by the FindSDL2.cmake
# module, but with modifications to recognize OS X frameworks and
# additional Unix paths (FreeBSD, etc).
