[Qt-interest] Reason for separate INCLUDEPATH and DEPENDPATH in qmake

[Daniel Price]

Welcome to the wonderful world of QMake! Automatic dependency tracking? Who needs it!

Seriously I've been bitten by this more times than I can count. Library dependencies are particularly insidious. In fact I've found the PRE_TARGETDEPS only seems to work if all projects are part of a SUBDIR which isn't always practical.

If you can, I recommend CMake instead.
