No, if you reference these static methods in your code the run time linker 
will want to resolve them at startup and at that time you haven't loaded 
these .la's yet.

That's not trivial I'm afraid. You would need to lookup the symbol with 
dlsym() but since it's a C++ method you don't know the symbol name.

The easiest way would be to use KConfigSkeleton::findItem("antialiasing") and 
then retrieve the value from the KConfigSkeletonItem that you get with 

See for example KConfigDialogManager::updateWidgets()
