I wrote a small patch to deal with hardcoded, nonstandard installation dirs.

Hello, I want to write an kdstatemachineeditor ebuild for gentoo portage. I am having trouble installing things where they are supposed by the standard to be installed, so I wrote this small patch for CMakeLists.txt.

I'm very much in favour of using GNUInstallDirs indeed. +1.

Superseded by #12 -- will discuss there.
