The flag is set to do the nightly build. See [https://github.com/Slicer/DashboardScripts/blob/4efec4e330f4e79da9d9eef3ac445a350bde4618/overload-vs2013-slicer\_release\_nightly.cmake#L57](https://github.com/Slicer/DashboardScripts/blob/4efec4e330f4e79da9d9eef3ac445a350bde4618/overload-vs2013-slicer_release_nightly.cmake#L57)
