Yes, this means that the Find-module requires cmake 2.8.3 I think.

Now, when you do a
find_package(KDE4)
before, CMAKE_MODULE_PATH is adjusted so that the files installed by kdelibs 
are used first.
They contain a FPHSA.cmake, which is not in sync with the most recent cmake 
release.

So what can be done
We can increase the required cmake version by kdelibs, but this won't help you 
until you require that newer vbersion of kdelibs.

You can work around it e.g. by tweaking CMAKE_MODULE_PATH, unset it before 
doing
find_package(Vc)
and restore it afterwards (of course while keeping the directory where 
FindVc.cmake is actually located).

Does that help ?
