How to create a standalone game?

[Sectonid]

So, what i know about this fork is that it's supposed to be compatible with most of Valve's Source Engine Games. However, because this is a leaked engine, its code is fully available and therefore allows to create a standalone game, rather than a mod. Is there any way to create a standalone game?
Edit: to be more clear, i want to create a game that compiles without any external Source Engine game.

Making standalone game with source sdk not running on Source Engine is illegal. Making standalone game with souce sdk running on leaked Source Engine is double illegal!

Oh, ok then.
