Hi,

When I set RxCocoa as a dependency (version 5.0.1) I see that Accio attempts to build RxSwift twice. From the logs:

✨  Found cached build products for RxSwift in local cache - skipping build.
✨  Found cached build products for RxRelay in local cache - skipping build.
✨  Found cached build products for RxSwift in local cache - skipping build.
✨  Found cached build products for RxCocoa in local cache - skipping build.

Seems like this is because RxCocoa depends on RxSwift and RxRelay, and RxRelay depends on RxSwift. Is this intended behaviour? Shouldn't Accio, after dependency resolution, only attempt to build the necessary dependencies once?

Thanks,
Andres
