With the release of version 4.1.0, a Unity plugin replicating the NuGet package is outputted to the build folder. You can simply drag and drop the contents into your Unity project. The plugin utilizes a runtime initiliazation script to ensure the native binaries are loaded when running in editor or standalone.
