    Cmake build wit qt(5|6)(macos) did not include "plugins"
    
    This makes things much simpler.
    
    But at least with the latest macos tools (Sonoma and XCode15) a bundle
    refuses to run if it 's not signed properly.
    
    Both issues are solved with the patch included and have now been tested
    with Qt5.15 and Qt6.7.
    
    For completeness: I've checked the font-emph shortcut issue and, as
    reported in the ticket mentioned, ^CmdE works with Qt5.15 but not with
    Qt6.7. However the sequence ^C E does work. I don't know whether this is
    intended as a workaround for this issue or was already implemented.
