Oh, but it is. Without this or cmake_policy(SET CMP0002 OLD) (see https://bugs.kde.org/show_bug.cgi?id=316308) applications that have their own translations in the tarball (everything we release from extragear) fails to build with a newer cmake. With this change in the kdelibs cmake modules it builds fine by setting a different target for each po folder.
