Generally if your dub.json or dub.sdl is configured correctly 
then all you need is to run "dub build" which will invoke package 
fetching etc. and then your desired compiler.

Dependencies are defined in dub.json / dub.sdl using 
"dependencies" which takes values as "packagename" and then 
"version".

Example: "vibe-d" "~>0.7.28"

I don't know if that helps.

I'm not familiar with Visual-D and don't use it at all, so I 
don't know if dub has to be used in specific ways. I compile 
though command line only, so.
