Compiled 7.4.20 not including library

Hi, compiling the PHP 7.4.20 version, where memcached is present, using the default web libtools configuration options, I have a problem recognizing --with-gd, --with-mcrypt and --enable-zip. I am unable to integrate the library later. How can I solve?

This is all because there is no memcached library that you can use in PHP80, which works fine instead.

Has anyone had the same problem as me? How did it solve?

I'm using Centos 8.

I can confirm that the default options in the OpenSpeedLite control webapp for compiling PHP 7.4.20 have the two hypothesized errors.

The configuration options must be written as indicated above.

Unfortunately for the third I have not found a solution.
