Usage: $programName [options]
  --configuration       Show the build directory for a specific configuration (e.g. Debug, Release.  Defaults to the active configuration set by set-webkit-configuration)
  --executablePath      Show the path to the executables produced by a specific build configuration. This differs from --configuration on Windows.
  -h|--help             Show this help message
  --top-level           Show the top-level build directory

  --gtk                 Find the build directory for the GTK+ port
  --wincairo            Find the build directory for using Cairo (rather than CoreGraphics) on Windows

Either --configuration or --top-level is required.
