That's no problem, other people responding can also keep you on CC.

If you use the attached file as a private, not-installed copy inside 
kdemultimedia this is fine with me.

But I would also be happy if we try to improve the FindFFmpeg.cmake in kdelibs 
so it does what you need. This file is quite straightforward and easy to 
understand.
Adding support for finding libswscale to it doesn't look to hard.
If you have a look at the file, you'll see what to do.
Basically add find_path() and find_library() calls for the respective files.
