When installing freeradius2 and sqlite3, schema.sql and dialup.conf missing


I installed freeradius2 and it is working fine if I save users in the file users.

Now I want to use SQLITE3, so I installed freeradius2-mod-sql and freeradius2-mod-sql-sqlite

To create the database I need schema.sql, and to setup all the queries used by freeradius I need dialup.conf.

If I search directly in github, using the 2.x branch but sqlite folder is missing:

Where should I get these files exactly? searching on the net I could not find them.

Any suggestion? Thanks a lot.
