No compiler can produce code for this Qt version – Apple silicon

  apple-silicon, c++, qt

I am trying to port a linux project to macOS. However I can’t even setup the build environment on an M1 Macbook Air 2020 (Apple silicon). I installed qt-creator, cmake, qt 5.15 and 6.1 using homebrew. I added the qt versions and cmake in the qt-creator settings. When I want to put everything together in the kits tab, I get the error in the title.

Checking the compilers tab, I realized that the autodetected clang compilers are x86 only. So I cloned the x86 clang++ entry and changed the ABI from x64 to arm. This should work I though, since clang++ is a unversial binary as file /usr/bin/clang++ reports

/usr/bin/clang++: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64e:Mach-O 64-bit executable arm64e]
/usr/bin/clang++ (for architecture x86_64): Mach-O 64-bit executable x86_64
/usr/bin/clang++ (for architecture arm64e): Mach-O 64-bit executable arm64e

What do I have to do?
