Doesn't look too bad, but I wouldn't commit it before there is something which 
also uses this.

One comment: you are using braces in an if-clause. This has been introduced to 
cmake in 2.6.3, we are still requiring 2.6.2. So if we don't upgrade our 
required cmake version, this can't go in.

I think for KDE 4.6 we'll require the most recent cmake version then (2.8.2 or 
2.8.3 I guess).

I fully support this, and I think it would be nice if the discussion about 
this would happen on a central KDE list, i.e. k-c-d or here.
