currently I'm using osxcross [1] on Linux to cross-build to macOS (and 
to Win and native Linux), either 32 (old OS ver only) and 64 bit, Intel 
and ARM, using gcc (old OS ver only) or clang, GNU libstdc++ (old OS ver 
only) and LLVM libc++.
I do that on Apple Intel HW so even the license is satisfied.
This work for CLI and even SDL2, GTK3 and QT5 app.
For GTK2 I cross-built a version targeting Quartz instead of the 
pre-built XQuartz with the help of a list friend.

To test the Intel binary without reboot to macOS/Intel you can use
macos-virtualbox [2]

As now I have no solution to virtualize macOS/ARM on Intel HW, so I ask 
to friends with new Apple silicon to test them. Someone know a working 
method?

Apple call static binary a binary that does not depend on OS syscall at all.
Anyway, also generating a binary that is statically linked (but even 
depend on sys dylib) is not so easy with osxcross.
Currently I collect and then modify all needed dylib to create a DMG 
package for my apps using a custom script.

on this I cannot help, I tested only C/C++ sources


In the past was asked to MXE to support macOS as target, hope once will 
be added.
