[FIXED] How do I switch source of memcache to compile and for drush to enable it?

Issue

Ubuntu 14.04 LTS Drupal 7.43 PHP 7.0

I read in other posts:

I switched to the https://github.com/rlerdorf/php-memcached.git, then I can successfully build the extension.

So how do I actually switch to the other git repo to build?

Because of php 7.0, my current memcache fails to build; error below:

sudo pecl install memcache
...
