[Gambas-user] How to soft depend on gambas3-gb-qt4-webkit

[Geoffrey De Belie]

This works, as long as you don't make changes to the class "HelpBrowser":
1) enable  gb-qt4-webkit,  gb-qt4 and disable gb-gui
2) compile everything
3) disable gb-qt-webkit, gb-qt4 and enable gb-gui

Is there a better way?
