Adding "hpp" as type does indeed result in the complete compilation of the 
generating product, before the using product is started. But the files were not 
recompiled if there were changes, so this only helps in the initial build.

What was I needed is also to Export cpp.treatSystemHeadersAsDependencies: true.
