Is it possible to make a library (dll/so) from separated .d files?

Hello. The title sounds weird, but I try to explain it better.

In Unreal Engine and Unity, source code files don't use main() 
and other important functions. They have only a class. Like this:

```
class SomeClass: someInterface
{
     AFunctionFromTheInterface1()
     {

     }

     AFunctionFromTheInterface2()
     {

     }
}
```

And then all the source code files will be compiled into a single 
.dll/.so library, so the game engine can use one in a game.

I don't know what compiler does Unreal Engine use, but it uses 
C++.

Is it possible to do so in D?
