[PyQt] Building SIP project

[Vicente Sole]

Take a look at the configure.py script of the PyQwt library. If I have  
properly understood the way it works, it takes care of that problem  
creating a temporary directory copying the files that have actually  
changed.

Look for the lazy_copy_file method in:

>    I have a SIP wrapper for a C++ library, consisting of
> about 60 .sip files. Things work quite well, but I have
> an issue with the process of creating the wrapper library.
> I use an (a bit adapted) configure script like it is shown
> in the documentation.

> The problem is that each small change to any of the .sip

> a "central" .sip file that includes all the others. And
> when I change any of those files and thus need to run
> the configure script all .cpp files are created anew.
> And then, of course, they're newer than the correspon-
> ding .o file and make will recompile all of them. That
> takes around 5 minutes and really slows development down.
> So I am looking for a way to tell sip to not re-create
> .cpp files when they aren't older than the correspon-
> ding .sip file or anything equivalent. Any ideas how
> to get this done?
