kmix failure in cmake

[Jonathan Riddell]

Anyone know what this failure when running kmix is about?

kmix hasn't changed, this was previously a cmake warning, now it's an
error and cmake return non-0 exit code.  Some policy must have changed
somewhere but I'm not sure what

CMake Error at /usr/lib/automoc4/Automoc4Config.cmake:248 (add_dependencies):
