codesigning executable embedded during buildPhase/copyFiles

Hi,

I'm using XCodeGen to generate an XCode project using an autotool project.

It is currently made of the following spec file:

name: VLC
options:
  bundleIdPrefix: org.videolan.vlc
  deploymentTarget:
    iOS: 9.0
targets:
  VLCAutomake:
    type: ""
    platform: ${VLC_PLATFORM}
    legacy:
      toolPath: /usr/bin/make
      passSettings: true
      attributes: $(ACTIONS)
      workingDirectory: ${VLC_BUILD_DIR}
    sources:
      - path: "${VLC_SRC_DIR}/src"
        excludes: "**/Makefile.in"
      - path: "${VLC_SRC_DIR}/include"
        excludes: "**/Makefile.in"
      - path: "${VLC_SRC_DIR}/modules"
        excludes: "**/Makefile.in"
  vlccoreios:
    type: "application"
    platform: ${VLC_PLATFORM}
    dependencies:
      - target: VLCAutomake
    info:
      path: "vlccoreios/Info.plist"
    sources:
      - path: ${VLC_BUILD_DIR}/test/vlccoreios
        type: file
        optional: true
        buildPhase:
          copyFiles:
            destination: executables

I'm basically building most of the targets from the automake target, and then use XCode to package them into an iOS or tvOS application.

However, the executable used in the vlccoreios target is not code signed and it doesn't seem that there is a way to sign it within the buildPhase, so it must be checked within the project each time it is generated again.

Is it possible to add the sign: true like for dependencies here?

Start with the VLCAutomake dependency and the vlccoreios source entry in the provided spec, focusing on the buildPhase/copyFiles configuration and generated Xcode project. Compare the generated project with the requested sign behavior and verify that the embedded executable is signed after regeneration.
