Add (or document?) Linux to MacOS Cross Building

[d3fault]

On the cross-building page there's Linux to Windows, Linux to Android, and Linux to iOS... but there's no Linux to MacOS. AFAIK, iOS and MacOS are not the same (but I don't use Apple products (despite wanting to deploy to them)). idk if the functionality exists in conan or if it just needs to be documented.

@d3fault I have no experience in cross-compiling from Linux to iOS/MacOS. is it even possible? do you have an example or document how to do it in general (without conan)?

Neither do we. That Conan documentation page tries to show examples about how to cross build with Conan, but it doesn't try to be a complete reference of cross-building between al systems, just a guide of how could you do it. I assume you would require a cross compiler first, that probably doesn't exist. As @SSE4 said, if you have further information about how to do it please write here and we could add it.

Also here explains more steps for creating the .dmg package: https://github.com/ddnet/ddnet/blob/master/README.md#cross-compiling-on-linux-to-macos

Thanks for the info. Do you have some feedback about the ABI compatibility between a library built with that toolchain (clang) and native's one (apple-clang)? Could they be used together to, for instance, create an executable?

I've transferred to the docs repository this issue.
