CM 13 stock launcher port for all Lollipop 5.0 and up version. Download and install as normal appno root required. But if you are rooted user then you can also move that file into /system/app folder.
But as you know there is no Notification badge on CM launcher. but you can use Xpose Gel app if you are rooted and Xposed installed in your mobile.
I m personally using this launcher and working fine without any issue or bug.
