Building a static library as a root doesn't build its dependencies

Bug Description

Building a static library as a root doesn't build its dependencies

How to reproduce?

Download and execute dub. You'll notice the log listed below it does find the dependency, but, it is only included as an importPath and it is not being actually built.

static_libs_dep.zip

Expected Behavior

I'm not even expecting it to combine the libraries, but I would at least like to it build all its dependencies. My usage is that I'm using dub to build the libraries and then move those libraries to use with another program.

was by design, use the new --deep flag to build dependencies as well for static libraries.
