Building KF5/Kate fails

[Dominik Haumann]

Building KF5 mostly works, except I now get the error (cleaned build + install
folder) below when building kate. It looks as if Qt4 is somehow in the way now.
This used to work before, so is there any way to get it working again?

The detailed cmake logs are on paste.kde.org (see below).

Greetings ;)
