Yeap:-)

If the libraries hardly ever change then you could install them (or put 
them into a absolute path somewhere). That is *ugly* as hell, but it 
will work woth bpth shadow building and in source building. I really 
suggest using the SUBDIRS approach.

Please do not confuse my rumblings here with "Nokia's advice"! I am just 
one developer and in no way willing or able to speak for Nokia as a whole.

Yes, documentation for qmake could be improved.

That can indeed happen occasionally. Touching the files in question 
should do the trick though.

Qt Creator has quite a bit of dependency setup in src/plugins. Maybe you 
can get some inspiration from there?

We are of course aware that there are issues with shadow building. Most 
of them are centered around resource usage (text files, pictures, etc.). 
The shadow build application will have trouble finding those if it tries 
to find them relative to its own location and they were shipped in the 
source tree.
