#   - RELEASE_CHANNEL: The release channel we're bundling ("oss").
#   - BUNDLE_ID: The app ID for the bundle ("com.galaxy.GalaxyOss").
#   - EXECUTABLE_PATH: The path to the compiled executable we want to install.
#   - BINARY_NAME: The name that the compiled executable should have on the target machine.
#   - ARTIFACT: Which artifact to build: app or cli.
