I've got it to work via:

$ cd DCD
$ dub build --build-mode=allAtOnce --combined
$ cd ..
$ ldc2 app.d DCD/dcd.lib

```d
void main(string[] args)
{
     init_dcd();
}

extern(C) void init_dcd() {}
```

ldc2 on Windows.

DCD/dcd.lib should be about 23mb.

I did have to hunt some files down, it seems some build commands in DCD 
isn't setup for this (almost certainly not using the environment 
variables that dub offers to handle this situation).
