Ok, the macro works fine now. Next problem is the following:

Linking CXX shared library ../../lib/libsmokekdecore.so
/usr/bin/ld: cannot find -lQt4__QTDBUS
collect2: ld returned 1 exit status

the cmake code is:
target_link_libraries(smokekdecore
    ${QT_QTCORE_LIBRARY}
    ${QT_QTNETWORK_LIBRARY}
    ${QT_QTDBUS_LIBRARY}
    ${KDE4_KDECORE_LIBS}
    smokeqtcore
    smokeqtnetwork
    smokeqtdbus
)

If I comment out the KDECORE libs, the above mentioned error goes away and I 
only get a whole lot of undefined reference errors (as was to be expected). So 
I guess FindKDE4Internal.cmake is doing something wrong. I just checked for 
updates, but my cmake macros are up-to-date.
