SDL2 CMake modules

This repository contains CMake modules for finding and using the SDL2 library as well as other related libraries:

• SDL2
• SDL2_image
• SDL2_ttf
• SDL2_net
• SDL2_mixer
• SDL2_gfx

These modules are based on the SDL (1.2) modules, with the same names, distributed with the CMake project. The SDL2_gfx module is also based on the SDL_image module.

Details and Improvements

The improvements made to these modules are as follows:

FindSDL2.cmake

• Adapt FindSDL.cmake to SDL2 (FindSDL2.cmake).
• Add cache variables for more flexibility:
  SDL2_PATH, SDL2_NO_DEFAULT_PATH
• Mark Threads as a required dependency for non-OSX systems.
• Modernize the FindSDL2.cmake module by creating specific targets:
  • SDL2::Core : Library project should link to SDL2::Core
  • SDL2::Main : Application project should link to SDL2::Main

For more details, please see the embedded documentation in FindSDL2.cmake file.

FindSDL2_<COMPONENT>.cmake

• Adapt FindSDL_<COMPONENT>.cmake to SDL2_<COMPONENT> (FindSDL2_<COMPONENT>.cmake).
• Add cache variables for more flexibility:
  SDL2_<COMPONENT>_PATH, SDL2_<COMPONENT>_NO_DEFAULT_PATH
• Add SDL2 as a required dependency.
• Modernize the FindSDL2_<COMPONENT>.cmake modules by creating specific targets:
  SDL2::Image, SDL2::TTF, SDL2::Net, SDL2::Mixer and SDL2::GFX.

For more details, please see the embedded documentation in FindSDL2_<COMPONENT>.cmake file.
