I've got the same problem as Scott. I've looked at those dot files with only moderate success, can anyone point me at more information about them (and the .hmap and .dep files)?
In my case, simply switching from one config to another and back (without building the 2nd config) will cause the following to happen: an included subproject that builds a private framework will think it needs to copy all its headers to the output directory, and then recompile all of its sources.
1) Why is it copying all the headers?
2) If I can't stop it, can I get it to preserve the timestamp so it won't trigger the recompile?
