Specify dependencies for binary distributed frameworks

Hello,

For my company, I'm taking care of building and distributing a framework.
This framework contains proprietary code, and therefore cannot be distributed through git/github.

The archive is building just fine, and is correctly uploaded to our server. The clients can integrate the framework in their projects.

Unfortunately, our framework has a few dependencies(see Cartfile below), and currently the only way for ours client to integrate our framework is to make them add our dependencies to their Cartfile.

Is there a way to specify dependencies for frameworks distributed with the *binary* scheme?

I suppose it's not that big of an issue because they would have to add our dependencies to *Linked Frameworks and Libraries* and */usr/local/bin/carthage copy-frameworks* anyway, but it would be a bit cleaner to make Carthage handle the dependencies for binary frameworks.

Could we add the framework's Cartfile to the archive, and use it to resolve the final app's dependencies?
Or have I missed something?

* `carthage version`: 0.22.0
* `xcodebuild -version`: Xcode 8.3.2 Build version 8E200
* Are you using `--no-build`? No
* Are you using `--no-use-binaries`? No
* Are you using `--use-submodules`? No
* Are you using `--cache-builds`? Yes
