Please provide a arm64 macOS way to compile

[YunaBraska]

Hi,

I would like to compile the game on my Apple Silicon (aarch64) machine. I have no idea about C and Visual Studio. Can you just provide a command or Unix script to install the dependencies and build the project? Would be awesome!

In theory, the Linux instructions should work, but there are some problems with the build on macOS. A while back, I even bought a Mac mini to try to address these build issues (which I can't recall off the top of my head), but I've been too busy to look at it.

This is supposed to work:

mkdir -p out/build/arm64-release
cmake --preset macos-arm64-release -B out/build/arm64-release
cmake --build out/build/arm64-release
ctest

and gets further in https://github.com/henricj/dunelegacy/tree/mac-build than the default "modernize" branch. But more work is needed.

Most of the problems seem to have been resolved when building with Xcode 15. In earlier versions, Xcode's poor std::ranges support had led to many compiler errors. There are still some linker issues, but everything is at least compiling now (on the mac-build branch, anyway).

It now compiles on macOS and the tests pass, but the main application fails soon after start (at least on an M2 mini running Sonoma 14.3.1).
