Re-build Apache with libapache2-mod-php?

Hello, I am trying to install a game panel control(https://pterodactyl.io/panel/1.0/webserver_configuration.html#apache-with-ssl), which requires libapache2-mod-php. How to rebuild apache with this module in WebServer Settings->Apache Rebuild? What option should I add?

I would like to 2nd rcschaff's hunch that you won't be able to succeed under CWP -- all the customizations for your game portal will likely not work or will cause CWP to stop working. You might be better off with a VM for Pterodactyl with Webmin for an admin interface.
