So do you still think cherry-picking of c8789dd6546c8fd8d00e4c0ed1ac8fa48d337acf into Applications/15.08 is required (I'm not sure because of the discussion)? Do other apps also have this line in Applications/15.08?

With the recent cmake changes to kdelibs>4.14.10 krdc fails to build with newer cmake versions with the error below. Adding the release-team, because it touches a dependency requirement and this patch might be nice to have in the 15.08.0 tarball.
