We are working on getting a new Ubuntu Plesk server running with memcached and keep running into errors when setting it up for PHP.
Using the instructions from Plesk we run the following successfully:
apt install memcached autoconf automake gcc libmemcached-dev libhashkit-dev pkg-config plesk-php*-dev zlib1g-dev make
But we run into an issue once we try to install the PHP extension (in our case for PHP 8.1)
/opt/plesk/php/8.1/bin/pecl install memcached
WARNING: channel "pecl.php.net" has updated its protocols, use "pecl channel-update pecl.php.net" to update
pecl/memcached can optionally use PHP extension "igbinary" (version >= 2.0)
pecl/memcached can optionally use PHP extension "msgpack" (version >= 2.0)

I noticed it referenced an error with the pecl channel at the beginning so I ran:
pecl channel-update pecl.php.net
But after the result was the same.
