Hello !

The variables are set in FindKDE4Internal.cmake.
Setting a variable directly 
set(FOO "some value")
overrides any existing variable with the same name from the cache.
So if there was already a variable with the same name in the cache, but a 
different value (e.g. FOO="bar" in the cache), this will be overridden.

We will probably change this in the buildsystem with the transition to KDE 

If you want to help, join us on the kde-buildsystem list :-)

Once more, a beginner (as I) has problems to anderstand why the settings
he is doing with ccmake are not token to build the flags.make-files .
The precedences of the settings are not clear, at the beginning of work.
It tooks me long time to find out what happens here.
