# - 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 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) # # $SDL2DIR is an environment variable that would # correspond to the ./configure --prefix=$SDL2DIR # used in building SDL2. # # 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). #============================================================================= # Copyright 2005-2009 Kitware, Inc. # Copyright 2012 Benjamin Eikel # # Distributed under the OSI-approved BSD License (the "License"); # see accompanying file Copyright.txt for details. # # This software is distributed WITHOUT ANY WARRANTY; without even the # implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # See the License for more information. #============================================================================= # (To distribute this file outside of CMake, substitute the full # License text for the above reference.) if(NOT SDL2_TTF_INCLUDE_DIR AND SDL2TTF_INCLUDE_DIR) set(SDL2_TTF_INCLUDE_DIR ${SDL2TTF_INCLUDE_DIR} CACHE PATH "directory cache entry initialized from old variable name") endif() find_path(SDL2_TTF_INCLUDE_DIR SDL_ttf.h HINTS ENV SDL2TTFDIR ENV SDL2DIR PATH_SUFFIXES include/SDL2 include ) if(NOT SDL2_TTF_LIBRARY AND SDL2TTF_LIBRARY) set(SDL2_TTF_LIBRARY ${SDL2TTF_LIBRARY} CACHE FILEPATH "file cache entry initialized from old variable name") endif() find_library(SDL2_TTF_LIBRARY NAMES SDL2_ttf HINTS ENV SDL2TTFDIR ENV SDL2DIR PATH_SUFFIXES lib ) if(SDL2_TTF_INCLUDE_DIR AND EXISTS "${SDL2_TTF_INCLUDE_DIR}/SDL2_ttf.h") file(STRINGS "${SDL2_TTF_INCLUDE_DIR}/SDL2_ttf.h" SDL2_TTF_VERSION_MAJOR_LINE REGEX "^#define[ \t]+SDL2_TTF_MAJOR_VERSION[ \t]+[0-9]+$") file(STRINGS "${SDL2_TTF_INCLUDE_DIR}/SDL2_ttf.h" SDL2_TTF_VERSION_MINOR_LINE REGEX "^#define[ \t]+SDL2_TTF_MINOR_VERSION[ \t]+[0-9]+$") file(STRINGS "${SDL2_TTF_INCLUDE_DIR}/SDL2_ttf.h" SDL2_TTF_VERSION_PATCH_LINE REGEX "^#define[ \t]+SDL2_TTF_PATCHLEVEL[ \t]+[0-9]+$") string(REGEX REPLACE "^#define[ \t]+SDL2_TTF_MAJOR_VERSION[ \t]+([0-9]+)$" "\\1" SDL2_TTF_VERSION_MAJOR "${SDL2_TTF_VERSION_MAJOR_LINE}") string(REGEX REPLACE "^#define[ \t]+SDL2_TTF_MINOR_VERSION[ \t]+([0-9]+)$" "\\1" SDL2_TTF_VERSION_MINOR "${SDL2_TTF_VERSION_MINOR_LINE}") string(REGEX REPLACE "^#define[ \t]+SDL2_TTF_PATCHLEVEL[ \t]+([0-9]+)$" "\\1" SDL2_TTF_VERSION_PATCH "${SDL2_TTF_VERSION_PATCH_LINE}") set(SDL2_TTF_VERSION_STRING ${SDL2_TTF_VERSION_MAJOR}.${SDL2_TTF_VERSION_MINOR}.${SDL2_TTF_VERSION_PATCH}) unset(SDL2_TTF_VERSION_MAJOR_LINE) unset(SDL2_TTF_VERSION_MINOR_LINE) unset(SDL2_TTF_VERSION_PATCH_LINE) unset(SDL2_TTF_VERSION_MAJOR) unset(SDL2_TTF_VERSION_MINOR) unset(SDL2_TTF_VERSION_PATCH) endif() set(SDL2_TTF_LIBRARIES ${SDL2_TTF_LIBRARY}) set(SDL2_TTF_INCLUDE_DIRS ${SDL2_TTF_INCLUDE_DIR}) if(BUILD_ENGINE_JS) set(SDL2_TTF_LIBRARY "sdl2_ttf_emscripten_internal") set(SDL2_TTF_LIBRARIES "sdl2_ttf_emscripten_internal") set(SDL2_TTF_INCLUDE_DIRS "${CMAKE_SYSTEM_INCLUDE_PATH}/SDL") endif() include(FindPackageHandleStandardArgs) FIND_PACKAGE_HANDLE_STANDARD_ARGS(SDL2_ttf REQUIRED_VARS SDL2_TTF_LIBRARIES SDL2_TTF_INCLUDE_DIRS VERSION_VAR SDL2_TTF_VERSION_STRING) # for backward compatiblity set(SDL2TTF_LIBRARY ${SDL2_TTF_LIBRARIES}) set(SDL2TTF_INCLUDE_DIR ${SDL2_TTF_INCLUDE_DIRS}) set(SDL2TTF_FOUND ${SDL2_TTF_FOUND}) mark_as_advanced(SDL2_TTF_LIBRARY SDL2_TTF_INCLUDE_DIR)
