# - Locate SDL2_ttf library (modified from Cmake's FindSDL_ttf.cmake)
|
|
|
|
|
# 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 compatiblity 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.
