Have SDL2::Core as a link dependency. This module will set the following variables in your project: :: 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 This module responds to the following cache variables: :: SDL2_TTF_PATH Set a custom SDL2_ttf Library path (default: empty) SDL2_TTF_NO_DEFAULT_PATH Disable search SDL2_ttf Library in default path. If SDL2_TTF_PATH (default: ON) Else (default: OFF) SDL2_TTF_INCLUDE_DIR SDL2_ttf headers path. SDL2_TTF_LIBRARY SDL2_ttf Library (.dll, .so, .a, etc) path. Additional Note: If you see an empty SDL2_TTF_LIBRARY in your project configuration, it means CMake did not find your SDL2_ttf library (SDL2_ttf.dll, libsdl2_ttf.so, etc). Set SDL2_TTF_LIBRARY to point to your SDL2_ttf library, and configure again. This value is used to generate the final SDL2_TTF_LIBRARIES variable and the SDL2::TTF target, but when this value is unset, SDL2_TTF_LIBRARIES and SDL2::TTF does not get created. $SDL2TTFDIR is an environment variable that would correspond to the ./configure --prefix=$SDL2TTFDIR used in building SDL2_ttf. $SDL2DIR is an environment variable that would correspond to the ./configure --prefix=$SDL2DIR used in building SDL2. Created by Amine Ben Hassouna: Adapt FindSDL_ttf.cmake to SDL2_ttf (FindSDL2_ttf.cmake). Add cache variables for more flexibility: SDL2_TTF_PATH, SDL2_TTF_NO_DEFAULT_PATH (for details, see doc above). Add SDL2 as a required dependency. Modernize the FindSDL2_ttf.cmake module by creating a specific target: SDL2::TTF (for details, see doc above). Original FindSDL_ttf.cmake module: 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). #]=======================================================================] # SDL2 Library required find_package(SDL2 QUIET) if(NOT SDL2_FOUND) set(SDL2_TTF_SDL2_NOT_FOUND "Could NOT find SDL2 (SDL2 is required by SDL2_ttf).") if(SDL2_ttf_FIND_REQUIRED) message(FATAL_ERROR ${SDL2_TTF_SDL2_NOT_FOUND}) else() if(NOT SDL2_ttf_FIND_QUIETLY) message(STATUS ${SDL2_TTF_SDL2_NOT_FOUND}) endif() return() endif() unset(SDL2_TTF_SDL2_NOT_FOUND) endif() # Define options for searching SDL2_ttf Library in a custom path set(SDL2_TTF_PATH "" CACHE STRING "Custom SDL2_ttf Library path") set(_SDL2_TTF_NO_DEFAULT_PATH OFF) if(SDL2_TTF_PATH) set(_SDL2_TTF_NO_DEFAULT_PATH ON) endif() set(SDL2_TTF_NO_DEFAULT_PATH ${_SDL2_TTF_NO_DEFAULT_PATH} CACHE BOOL "Disable search SDL2_ttf Library in default path") unset(_SDL2_TTF_NO_DEFAULT_PATH) set(SDL2_TTF_NO_DEFAULT_PATH_CMD) if(SDL2_TTF_NO_DEFAULT_PATH) set(SDL2_TTF_NO_DEFAULT_PATH_CMD NO_DEFAULT_PATH) endif() # Search for the SDL2_ttf include directory find_path(SDL2_TTF_INCLUDE_DIR SDL_ttf.h HINTS ENV SDL2TTFDIR ENV SDL2DIR ${SDL2_TTF_NO_DEFAULT_PATH_CMD} PATH_SUFFIXES SDL2 # path suffixes to search inside ENV{SDL2DIR} # and ENV{SDL2TTFDIR} include/SDL2 include PATHS ${SDL2_TTF_PATH} DOC "Where the SDL2_ttf headers can be found" ) if(CMAKE_SIZEOF_VOID_P EQUAL 8) set(VC_LIB_PATH_SUFFIX lib/x64) else() set(VC_LIB_PATH_SUFFIX lib/x86) endif() # Search for the SDL2_ttf library find_library(SDL2_TTF_LIBRARY NAMES SDL2_ttf HINTS ENV SDL2TTFDIR ENV SDL2DIR ${SDL2_TTF_NO_DEFAULT_PATH_CMD} PATH_SUFFIXES lib ${VC_LIB_PATH_SUFFIX} PATHS ${SDL2_TTF_PATH} DOC "Where the SDL2_ttf Library can be found" ) # Read SDL2_ttf version if(SDL2_TTF_INCLUDE_DIR AND EXISTS "${SDL2_TTF_INCLUDE_DIR}/SDL_ttf.h") file(STRINGS "${SDL2_TTF_INCLUDE_DIR}/SDL_ttf.h" SDL2_TTF_VERSION_MAJOR_LINE REGEX "^#define[ \t]+SDL_TTF_MAJOR_VERSION[ \t]+[0-9]+$") file(STRINGS "${SDL2_TTF_INCLUDE_DIR}/SDL_ttf.h" SDL2_TTF_VERSION_MINOR_LINE REGEX "^#define[ \t]+SDL_TTF_MINOR_VERSION[ \t]+[0-9]+$") file(STRINGS "${SDL2_TTF_INCLUDE_DIR}/SDL_ttf.h" SDL2_TTF_VERSION_PATCH_LINE REGEX "^#define[ \t]+SDL_TTF_PATCHLEVEL[ \t]+[0-9]+$") string(REGEX REPLACE "^#define[ \t]+SDL_TTF_MAJOR_VERSION[ \t]+([0-9]+)$" "\\1" SDL2_TTF_VERSION_MAJOR "${SDL2_TTF_VERSION_MAJOR_LINE}") string(REGEX REPLACE "^#define[ \t]+SDL_TTF_MINOR_VERSION[ \t]+([0-9]+)$" "\\1" SDL2_TTF_VERSION_MINOR "${SDL2_TTF_VERSION_MINOR_LINE}") string(REGEX REPLACE "^#define[ \t]+SDL_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 ${SDL2_TTF_INCLUDE_DIR}) include(FindPackageHandleStandardArgs) FIND_PACKAGE_HANDLE_STANDARD_ARGS(SDL2_ttf REQUIRED_VARS SDL2_TTF_LIBRARIES SDL2_TTF_INCLUDE_DIRS VERSION_VAR SDL2_TTF_VERSION_STRING) mark_as_advanced(SDL2_TTF_PATH SDL2_TTF_NO_DEFAULT_PATH SDL2_TTF_LIBRARY SDL2_TTF_INCLUDE_DIR) if(SDL2_TTF_FOUND) # SDL2::TTF target if(SDL2_TTF_LIBRARY AND NOT TARGET SDL2::TTF) add_library(SDL2::TTF UNKNOWN IMPORTED) set_target_properties(SDL2::TTF PROPERTIES IMPORTED_LOCATION "${SDL2_TTF_LIBRARY}" INTERFACE_INCLUDE_DIRECTORIES "${SDL2_TTF_INCLUDE_DIR}" INTERFACE_LINK_LIBRARIES SDL2::Core) endif() endif()
