I'm getting this while building with meson:

src/meson.build:151: WARNING: Passed invalid keyword argument "win_subsystem".
WARNING: This will become a hard error in the future.

[albfan]

this argument was ``gui_app:true` prior to meson 0.56. After that version, it is deprecated but still works.

See it on https://mesonbuild.com/Reference-manual.html#executable

Looks that's what happen, seing ubuntu meson package:

https://packages.ubuntu.com/search?keywords=meson

windows msys2 version is patched with +0.56 meson:

https://github.com/msys2/MINGW-packages/blob/master/mingw-w64-akira/Avoid-open-cmd-terminal-running-on-windows.patch

But will rework this to avoid patches for next releases

Converting this to Draft so we know it needs some work.
Feel free to mark it ready for a full review once the issue with meson is fixed.

I'm on meson 0.58, should I do conditional compilation for meson >0.56
