Assuming I have a `Package.swift` like this below, and `SomePackage` from the dependencies produces warnings during `swift build`. 

```swift
// swift-tools-version:4.0
import PackageDescription

let package = Package(
    name: "my-app",
    dependencies: [
        .package(url: "https://some-package.git", .upToNextMajor(from: "1.0"))
    ],
    targets: [
        .target(name: "Run", dependencies: ["SomePackage"]
    ]
)

```

How can I suppress those warnings from the dependencies, but keep the ones coming from my code?
