Thanks for the advice.

In case someone else has the same problem:

It turned out that my upgrading my Qt4 from 4.3.2 to 4.3.3 
 previously having cmake:ed the same source had left a cache  file
in the Source (!!) tree as well as in the build directory.
I usually use a symlink to point to the current version of both
kde and Qt and then have this in my PATH, in this case the link was
/usr/local/Trolltech/Qt-4 -> /usr/local/Trolltech/Qt-4.3.3 and the PATH
/usr/local/Trolltech/Qt-4/bin
The cache file contained the absolute path to moc et al. for some reason
and thus it tried to use the old removed version of them.
Removing both cache files (CMakeCache.txt) got me forward on this.
But cmake could have told me "
/usr/local/Trolltech/Qt-4.3.2/bin/moc not found"
instead of: moc not found.

=== Start rant ====

And the main issue still remains though:
cmake is VERY MUCH lacking a trace possibility and I haven't had
to spend more time finding out "what it wants this time"  since 
compiling/porting things before automake et al. 10-15 years ago.
I still think cmake was a bad choice for KDE4.

=== End rant ===

Best and thanks
