kdewidgets designer plugin not built correctly

[Matt Rogers]

Hi,

the kdewidgets.so library that hold all the kde widget plugins for use
in designer is not being built correctly. There are several issues:

1. kdewidgets.cpp is not regenerated if makekdewidgets has to be rebuilt
due to a change in the code or after a 'make clean' in the kdewidgets
directory.

2. kdewidgets.so does not contain the symbols from kdewidgets.o that is
built from kdewidgets.cpp (at least that's what i see when looking at
the output of nm)

3. kdewidgets.la is not recreated during the build process after a 'make
clean'. doing a 'make clean && make && make install' results in an error
from cmake about kdewidgets.la not being found. 

AFAICT, the CMakeLists.txt file in kdelibs/kdewidgets looks fine but
perhaps somebody else could take a look.

Thanks
