Nothing:-)

You can set the other build tools in the kit, but since Qbs is linked
into creator there is nothing to set.

That is actually a huge problem since qbs changes so much that you
need to closely match the Qt Creator version you use to the code you
want to build with it.

Best Regards,
Tobias
