You're right - it is processing all of the Qt and KDE stuff that you import. 
For example, if you have classes (which you almost certainly do) that 
subclass QObject or QWidget, their header/sip files contain only the 
information about the methods that the  class's new methods or the inherited 
methods that it overloads.

However, when you use the new class, you expect to be able to access any 
method inherited from QObject or QWidget, so sip has to generate bindings 
(within the new class) for all of those methods as well, and to do that, it 
needs to know what those methods are - exactly the same as gcc/g++ needing to 
see qobject.h, etc.
