I treat my dependency files exactly the same as my object files, so I
keep them in a separate tree. If you prefer to keep your object files in
the source tree I'd just put my dependency files in the source tree too.

I don't have a separate step to create the dependency info either.
Have a look at 
http://www.cmcrossroads.com/option,com_smf/Itemid,180/topic,69672.0.html
The final solution is actually quite easy to use and write (Once you
know how it works of course).
