Two things:

 1. -xcb is passed twice: once uncoditionally on the Qt version, and
    once for each Qt version;

 2. The build failure you reference is about a qt-5.12 build, which
    complains about an "Invalid value given for boolean command line
    option 'xkbcommon'".

So, it looks like qt-5.12 does not linke -xkbcommon, but this is exactly
what you are passing with this patch...

Did I misunderstand something?

Cordialement,
Yann E. MORIN.
