Has anyone got memcached to work on Laravel Homestead php7 box?

I loaded up Laravel/Lumen on the new Homestead php7 box and encountered this error:

FatalThrowableError in MemcachedConnector.php line 51:
Fatal error: Class 'Memcached' not found

Doing a phpinfo(); shows there is no memcached extension, but sudo service memcached status says memcached is running. It seems there is a php7 branch for memcached here: http://ift.tt/1jpRmZn

Can anyone guide me on how to get it working in the new php7 Homestead VM?

EDIT: I just saw on the homestead install documentation that it says "Memcached (PHP 5.x Only)". Question still remains on how to get it working. But also I'd like to know what the recommended cache/session driver for Laravel/Lumen in php7 should be for now?
