Currently the binary target feature in the Swift Package Manager only works for single binary dependencies. The API for `Target` is shaped so that its own static method for returning a `.binaryTarget` does not take a `dependencies` array like the standard `.target` method.
Setting the `dependencies` property on a `Target` type when that type is `binary` results in a crash to the SPM.
There is a workaround for the including dependencies in binary targets but it includes adding a dummy target to your `package.swift` and the result also generates warnings in an integrator's xcode project.
The desired change to the SPM is to allow `binaryTarget`s to declare `dependencies` in their `package.swift` files.
