How to install murrine theme openSUSE 13.1

I hear that murrine theme for GTK is very customizable. I want to install this theme.
I installed this package by zypper: gtk2-engine-murrine.

However, I can’t see murrine in Desktop Configuration >> Appearance >> GTK >> GTK 2.0. I also don’t see murrine in /usr/share/themes/ directory

What am I missing? What do I need to install it?

Thank you
