* SDL2 or SDL3 (see below)
Aside from standard search options (`ZLIB_INCLUDE_DIR`, `ZLIB_LIBRARY`, ...) the following options are available:
* `ENABLE_OPENGL` - Enable OpenGL driver
* `ENABLE_OPENGL3` - Enable OpenGL 3+ driver
* `ENABLE_GLES2` - Enable OpenGL ES 2+ driver
* `ENABLE_OPENGL` - Enable OpenGL driver
* `ENABLE_OPENGL3` - Enable OpenGL 3+ driver
* `ENABLE_GLES2` - Enable OpenGL ES 2+ driver
* `USE_SDL3` (default: `OFF`) - Use the SDL3 device instead of SDL2 (**experimental**)
**However, IrrlichtMt cannot be built or installed separately.**

This doesn't mean other platforms don't work or won't be supported, if you find something that doesn't work contributions are welcome.
Compatibility matrix
--------------------
Driver (rows) vs Device (columns)
| | SDL2 [1] | SDL3 [2] |
|---------------------------|----------|----------|
| OpenGL 1.2 (to 2.1) | Works | Testing |
| OpenGL 3.2+ | Works | Works |
| OpenGL ES 2.x | Works | Testing |
| WebGL 1 | ? | ? |
| Null (no graphics output) | Works | Works |
Notes:
* [1] `CIrrDeviceSDL` with `USE_SDL3=0`: supports [many platforms](https://wiki.libsdl.org/SDL3/README-platforms)
* [2] `CIrrDeviceSDL` with `USE_SDL3=1`
