Configure memcached with and enable-sasl Ubuntu 16.04

Your memcached tutorial is outdated and primarily focused on php. I have searched but cannot find a straightforward guide to setup memcached, with sasl enabled. If I make memcached myself it complains that it cannot find libevent. Even though libevent is installed. I cannot seem to find any clear instruction on how to install memcached using apt install and enable sasl, during install or post install.

How can I set up memcached securely by enabling sasl and configure remote access (I assume using iptables). And yes, I have searched. If someone could assist, I would be greatful. Thank you
