kdelibs build fails with installed Qt

[David Jarvie]

I've been getting a cmake error trying to build the latest snapshot. It turns 
out that the problem is that I *installed* Qt after building it, rather than 
simply using it in the build tree, and the kdelibs cmake system doesn't cope 
with that.

I had to fiddle things a bit to try to get it to work, so I don't know exactly 
what is necessary to fix the build. But the kdelibs cmake build process seems 
to use at least two Qt components which are currently not installed in the Qt 
install process. (I used the following command line to install Qt, so as to 
omit the Qt examples:

make sub-src-install_subtargets sub-tools-install_subtargets install_htmldocs

I couldn't find any other install target to rectify things.)

The missing Qt components are:
- the mkspecs directory (or perhaps just the relevant part of it?). 
- qmake.
