Add support for custom modules?

Let's say I want nginx cache purge module or any other module. Script installer has to compile the module and all other things that are required by himself.
This script should give an option where Script installer can input the path to module folder.
Like this: ( I'm not a programmer: 100: )

> Do you want to add extra modules ( yes/ no ): Y
> Please confirm, you have compiled your modules or anything that is required. We'll not responsible for any errors.
> Continue adding moodules (yes/no)? Y (ENTER)
> Input the path to module(s) folder (eg: /opt/module/ ): /usr/local/nginx_cache_purge/ (ENTER)
> Continue adding moodules (yes/no)? Y (ENTER)
> Input the path to module(s) folder (eg: /opt/module/ ): /usr/local/nginx_redis/ (ENTER)
> Continue adding moodules (yes/no)? Y (ENTER)
> Input the path to module(s) folder (eg: /opt/module/ ): /usr/local/modsecurity/ (ENTER)
> Continue adding moodules (yes/no)? NO (ENTER)
> All modules are added and ready to be compiled with nginx, press any key to continue:
