PostgreSQL db password policy

Can you assist me with configuration for passwordcheck_extra.

In README file it's mentioned that :

1) Copy it as contrib/passwordcheck_extra in PostgreSQL code and use the
following command:
make install

I am using Windows operating system, So I need to copy passwordcheck_extra.sql in C:\Program Files\PostgreSQL\9.5\share\contrib , correct ?

Then, where to run make install command to make it available?

Reagrds,
