Implementing -iframework is certainly important if KDevelop is to integrate better on OS X .
But there are 2 things that I think we should understand first:

- why does -isystem /path/to/QtCore.framework/Headers not enable resolving e.g. `#include <QCoreApplication>` given that /path/to/QtCore.framework/Headers contains both QCoreApplication and qcoreapplication.h ?
- why does KDevelop4 not have this issue?
