Autogenerate source directory

[own2pwn]

I believe it'd be nice to have an option / autogenerate source tree root when you're defining new target. Am I missing an existing option?

Maybe use a template?

I have one globally available on my machine for Swift Packages:

targetTemplates:
  SwiftPackage:
    type: framework
    platform:
      - iOS
      - macOS
      - tvOS
      - watchOS
    platformSuffix: " (${platform})"
    sources:
      - "Sources/${target_name}"

The takeaway point is the use of ${target_name} in templated sources.
