# 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:<br>
|
|
`SDL2_PATH`, `SDL2_NO_DEFAULT_PATH`
|
|
- Mark `Threads` as a required dependency for non-OSX systems.
|
|
|
|
*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:<br>
|
|
`SDL2_<COMPONENT>_PATH`, `SDL2_<COMPONENT>_NO_DEFAULT_PATH`
|
|
- Add `SDL2` as a required dependency.
|
|
|
|
*For more details, please see the embedded documentation in
|
|
`FindSDL2_<COMPONENT>.cmake` file.*
