Conditions on artifacts do not work or at least not the way one might 
think they do. If you need a dynamic number of output artifacts, please 
use a Rule instead of a Transformer (just make up some tag that only 
matches your version.h.in file). There, use the "outputArtifacts" 
property instead of "Artifact" items. See 
http://qt-project.org/doc/qbs-1.2/rule-item.html for details.
