Include dynamic library from repo I don't own on GitHub

Using Swift

I want to include a dynamic version of a library that has not explicitly declared itself as dynamic. Similar to the following.

import PackageDescription

let package = Package(
    name: "MyPackage",
    products: [
        .library(
            name: "MyPackage",
            targets: ["MyPackage"]),
    ],
    targets: [
        .target(
            name: "MyPackage",
            dependencies: []),
    ]
)

Does this mean that I must fork the library and provide a dynamic version of it myself?

import PackageDescription

let package = Package(
    name: "MyPackage",
    products: [
        .library(
            name: "MyPackage",
            targets: ["MyPackage"]),
        .library(
            name: "MyPackage",
            type: .dynamic,
            targets: ["MyPackage"]),
    ],
    targets: [
        .target(
            name: "MyPackage",
            dependencies: []),
    ]
)
