I’m running:
Nginx 1.10
PHP7.0.6-dev
Ver 15.1 Distrib 10.0.23-MariaDB
…on a Raspberry Pi 2B

phpinfo(); says memcached version 3.0.0b1, libmemcached version 1.0.18

Simple Cache says “Neither Memcache or Redis PHP extensions are set up on your server.”
How does the plugin determine whether or not memcached is installed?

Thanks!
