How to script accept multiple licenses?

This:

Controller.prototype.LicenseAgreementPageCallback = function()

{ var widget = gui.currentPageWidget(); widget.AcceptLicenseRadioButton.checked = true; gui.clickButton(buttons.NextButton); }

worked in 3.2.3, but not 4.1.1. Because CMake has been selected, its license must now also be accepted. Where is the documentation on how multiple licenses can be selected? Adding --accept-licenses to the command-line does nothing.
