Ok, so you want to build a 32bit application, but cmake gives you the 64bit 
libraries.
Should the 32bit libraries be located in /usr/lib/ ?

I think this would mean that two builds of kdelibs would be installed to the 
same prefix. Lots of things would be overwritten in this case, header files, 
data files, executables.
Which behaviour would you expect ?
What do other projects do ?

I think until now we don't support this at all.
Right now I would recommend to install a 32bit-kdelibs e.g. to /opt/kde4-32/, 
and the 64bit-kdelibs to /usr/, or something like this.
