Thank you very much for your detailed answer. I got dynamic 
bindings running now. But you said static bindings are the main 
portion of bindings we use. So I tried to get static Lua bindings 
going. I got the static library `liblua.a` and I told my linker 
in the dub.json file where to find it:

```json
   [...]
   "versions": ["LUA_52"],
   "lflags": ["-L/usr/local/lib/liblua.a"],
   [...]
```

This works perfectly fine. I can also use `"libs": ["lua"]` so I 
don't have to specify the complete path. But now I wonder, do I 
have to specify all static bindings via linker commands or is 
there a mechanism which allows me to specify a path where all the 
libraries can be found? And my other question is, if I have to 
specify all static libraries by name, how do I know the name of 
the library? Giving the system path as `lflag` is easy, but where 
does Lua get the `lua` name from which works in the `"libs": 
["lua"]` string?

Thanks for answering my noob questions. I've never dealt with 
bindings and compiler flags in the languages I come from. :P
