No, because KOrganizer also needs the XML files and we don't want it to depend 
on KMail. I used the solution below.

This seems to work, at least Dashbot didn't complain yet. Thanks very much for 
your help.
The build error I had was actually forgotten add_dependencies... But this 
solution is the best, as other parts only depend on the XML file, not on the 
whole KMail.
