Run without Vapor

[codeOfRobin]

Running swift build with purely vapor-apns yields a bunch of errors around compiling CTLS. (here's what the dependencies in Package.swift look like, in case it isn't clear:

 .Package(url:"https://github.com/matthijs2704/vapor-apns.git", majorVersion: 2, minor: 0)

Adding Vapor, however, compiles successfully.

Is there any way to run this package without vapor, for simple scripting purposes and the like? (possibly adding whatever dependencies of Vapor allow CTLS to compile successfully?)
