Do something useful when "building" targetType none packages

[s-ludwig]

Either an informative error message should appear, or, when sub packages exist, DUB could build all sub packages instead for example See also #87.

Some thought should probably be given to how this interacts with sourceLibrary packages. In the case that the sourceLibrary is being referenced by a downstream build, one might only want to build the subpackages if they're dependencies of the sourceLibrary -- but if one issues dub build in the root directory of the source library itself, it can probably be assumed that all subpackages should be built.

Is this still planned?

[s-ludwig]

Yes, it just has relatively low priority.

Is there a nice-ish workaround for now so I don't need to use a bash script?

[LightBender]

bump I know it's a low priority but it would be very helpful when working on large scale projects with many components and dependencies.

[SimonN]

bump -- I'd love to build two target binaries.

Or are there idiomatic solutions, besides running dub twice e.g. from a script/makefile?
