Please update your FindKDE4Internal.cmake, I committed a change so that now 
KDE4_INSTALL_DIR is determined relative to the location of the installed 
FindKDE4Internal.cmake instead of kde4-config.exe. This should help for now 
for this problem.

Ok, I lost track.
How does it call makekdewidgets, how does it call kde4automoc, and which of 
the two is the problem ?

Is libQtUiTools.a a static or a shared library ? 
Don't they usually have the suffix .dll or .lib ?
