1. Installed memcached via PHP Pecl Module Installer for PHP 7.3, no problem
2. Did yum install libmemcached as root, installed OK (black terminal screen below)
3. Install memcached via PHP Pecl fails due to it not being able to find libmemcached.
If I knew precisely what command was being run with PHP Pecl, and I knew where libmemcached was installed, I could take the advice of using --with-libmemcached-dir= but if I'm going to be running the command myself then the Module Installer is kind of useless and broken in this case, or it's user error. Help?

SOLVED: yum install libmemcached-devel
Apparently that has to be there too. Strange that the PHP Pecl module installer output doesn't mention that.
