Swift 包：找不到依赖包。补救？

Question

背景： 我今天早些时候使用不同的依赖项作为 'proof of concept' 创建了一个 successful package <--- dependency。

然而 Facebook SDK 包 依赖项未能被识别：

这里是 package.swift:

// swift-tools-version:5.3
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "CVSFacebookAccess",
    platforms: [
           .iOS(.v13)
       ],
    products: [
        // Products define the executables and libraries a package produces, and make them visible to other packages.
        .library(
            name: "CVSFacebookAccess",
            targets: ["CVSFacebookAccess"]),
    ],
    dependencies: [
        .package(name: "Facebook", url: "https://github.com/facebook/facebook-ios-sdk.git", from: "11.0.1")
    ],
    targets: [
        // Targets are the basic building blocks of a package. A target can define a module or a test suite.
        // Targets can depend on other targets in this package, and on products in packages this package depends on.
        .target(
            name: "CVSFacebookAccess",
            dependencies: ["Facebook"]),
        .testTarget(
            name: "CVSFacebookAccessTests",
            dependencies: ["CVSFacebookAccess"])
    ]
)

这是 Facebook 包：

问题：
为什么无法识别Facebook SDK？
我正在关注相同的 Swift PM syntax as before.

iOS 包的 Facebook SDK 包含几个库，例如：FacebookCore、FacebookLogin、FacebookShare、FacebookGamingServices，您应该依赖于一个需要的，例如：

...
.target(
    name: "YourPackage",
    dependencies: [.product(name: "FacebookLogin", package: "Facebook")]),
...

然后你就可以在你的代码中使用这个库了：

import FBSDKLoginKit

func createLoginButton() -> FBLoginButton {
    return FBLoginButton()
}
