Error when building generated cpp code

[bentxt]

Hi,

After building Lobster from source and after following the steps needed to compile hello.lobster to compiled_source.cpp I get this error

cmake version 3.26.4

CMake suite maintained and supported by Kitware (kitware.com/cmake).

Well, that has little to do with the generated cpp code, it is simply the included SDL library doesn't compile anymore with your up to date compilers.

We'll need to update the included SDL.

The included SDL has been updated.

Should build on Mac with CMake, I needed cmake .. -G Xcode -DSDL_HIDAPI_JOYSTICK=OFF -DSDL_JOYSTICK=OFF -DSDL_HAPTIC=OFF to make it work, not yet sure why.

Included Xcode project still broken, will likely remove it in favor of cmake.
