I am on Windows so the killall does not work. But I figured this out (enter the values in the same form that Julien has posted as a screenshot):

Command: taskkill

Arguments: /FI "STATUS eq Running" /IM APPNAME.exe /F

You need to replace APPNAME with your application's name, of course. The /FI "STATUS eq Running" is a filter that enables qmake to proceed after this pre-build-step, even if the application is not yet running (else it would not find the process to kill and then exit). Without the /F the application won't get closed, at least for me.

However, if your application has a icon in the trayarea, the icon won't disappear. The icon gets removed when you move the mouse over it.
