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
