Can't set custom compiler options (apple's arm64 cross to x86-64)

[asc7uni]

Hello. I am trying to compile for x86-64 using apple's clang++.

I created custom compiler and added options for cross compilation: -arch x86_64

But when running build with this compiler (I checked twice that I am using correct kit and that this compiler is selected) I have linkage error. And I see in output that clang was called with -arch arm64 argument:

What am I missing to build x64 build on arm64 platform?

Which build system are you using?

CMake

I managed to build with XCode so in theory this should be possible in QtCreator too
