This looks very much like 
https://bugreports.qt-project.org/browse/QBS-370. The tentative plan is 
to have this working in a generic way in qbs 1.2.
However, if the maximum number as well as the actual number of outputs 
are known statically (which seems to be the case here), it could work 
already.

This looks like the right approach. Have you tried it?
