cmake Kubuntu merge

[Jonathan Riddell]

Ubuntu has opened a new development version, so we are doing merges
from Debian.

First is cmake, due to popular demand this has an added build-dep on qt 4 and builds a cmake-gui
package.

To keep the delta minimal it still installs to debian/cmake and copies
the files to debian/cmake-gui, if Debian would pick up the changes I'd
be happy to change it to installing to debian/tmp and doing the normal
thing with .install files.
