[SailfishDevel] Harmattan to Sailfish Migration: QCamera not found

Tue Apr 9 19:17:45 UTC 2013

Ciao Guillermo

Thanks, that cracked it, QCamera is now found - I'm onto the next  
error, but that is the subject of another mail.

Is there any easy way of finding out in which Sailfish / Mer package a  
particular Qt Object lurks? On the Harmattan SDK everything was  
installed upfront, so I did not have to worry about where things were.  
Sailfish seems to take a more minimalist approach, which is fine, but  
I don't want to have to write repeated "where is xxxx mails" if I can  
help myself.

Grazie

Chris
