Older cmake versions have issues with the latest sdl2 release because it includes `.m` objective-c sources, for which CMake has only added support [in recent versions](https://cmake.org/cmake/help/latest/command/enable_language.html). Also, `-x objective-c` means...

The downside of my proposal to use `enable_language(OBJC)` is that is increases the required CMake version to 3.16 (for Apple systems) An alternative could be to add the following: ```cmake...

Can you please post the error log for a clean build of sdl2/sdl2-static? Because perhaps the error is because some objective-c header is included in a C source.

Thanks for the log. Curiously, it passes `-x c` to the compiler which means it interprets the source as c. This really should not happen. Have you confirmed that the...

Your logs contain ```cmake set(CMAKE_C_SOURCE_FILE_EXTENSIONS c;m) ``` Can you try adding the following after `enable_language(OBJC)` (without adding `OBJCXX`) ```cmake list(REMOVE CMAKE_C_SOURCE_FILE_EXTENSIONS m) ```

Are you building sdl standalone or as a subproject? Can you try doing: ```cmake project(SDL2 C CXX OBJC) ``` at the top of our cmake scrip? (instead of we doing...

`FetchContent` is basically doing `add_subdirectory`. To iterate faster, you should be able to fetch from a local repo and replace the argument of `GIT_REPOSITORY` with a path on your filesystem....
