Looks like original port author, Kycok, abandoned his work and doesn't want to update this anymore (latest update were 2 years ago!). So I give this work in my hands. :)
In original port has been missing symlinks for Plasma 5 to work properly (existed symlinks stays still). I fixed many often used, such as "Help Select", "Link Select", resizing window in all directions and so on.

Installing: 1. Simply extract folder "pixelfun3" in "/home/username/.icons" (~./icons) and apply scheme via System Settings - Workspace Theme - Cursor Themes.
2. You can use the OCS-Store app to install it.
