xcodebuildresources doesn't respect folder structure

Specifying files via xcodebuildresources doesn't appear to respect the folder structure. For example:

Real path:
shaders/
  - vertex.vert
  - fragment.frag

Virtual path:
Resources/
  - shaders/
    - vertex.vert
    - fragment.frag

Adding the following to the Premake scripts:

xcodebuildresources {
  "shaders",
}

Results in the files being bundled, but in the root directory rather than the shaders directory. I'm not 100% sure how XCode handles it, I tried to replicate the project configuration with Premake but the xcodeproj file was "corrupt" and wouldn't load.

Start at the xcodebuildresources entry point in the Premake scripts and inspect the generated xcodeproj configuration for the resource path. Reproduce the shaders example, then verify that vertex.vert and fragment.frag remain under Resources/shaders rather than the bundle root; done when the generated project loads and preserves that layout.
