It is unlikely that kdelibs has parts of a this recent CMake version
included, since most parts of the cross compiling support seem to be
older than 2 years.
Since I am not the CMake maintainer (of OpenEmbedded), and also have
only limited CMake experience, I will try that one out last.

The files exist in the hosts sysroot too, but I already checked that,
they are not used.
For now I will see if changing the
KDELibs4LibraryTargets-relwithdebinfo.cmake works, and how to alter
the method they are created.
