Building desktop client for Mac

Hi,

I am trying to build the 3.15.3 desktop client for Mac.

I found no documentation about how to set up my environment so I “followed” somehow the GitHub CI steps described here :

But the call to craft with -c --install-deps nextcloud-client results in Qt build errors…

CMake Error at Qt6QmlIntegrationVersionlessAliasTargets.cmake:3 (_qt_internal_check_multiple_inclusion): Unknown CMake command "_qt_internal_check_multiple_inclusion".

Am I doing something wrong ? Missing something ?
