Answering myself, for the posterity :-)

This error is not related to namespacing, but really to the fact that 
the include files were not found: I add to add this line

   headers.fileextensions += *.h

to my qdocconf file, or qdoc wouldn't find my headers. AFAIU, this line 
is not present in many other qdoc projects only because it's already 
defined by some qdoc file included by the main one.

Ciao,
