Maybe this will help you:

I think it falls under the something else category. The "lib" 
folder does have a source directory but I'm pretty sure you can 
remove that and it will still work and compile only the sub 
projects you want it to.

But, dub is sometimes a mystery in how it works so shout if the 
above doesn't work!
