Cannot profile QML applications

If I try to profile a Qt Quick application I get the error message "Could not connect to the in-process QML profiler". When I click on "Help" it says
"Select Projects, and then select the Link QML debugging library check box in Build Steps.
You might have to compile the library first, by selecting the Compile link."
Unfortunately there is neither a "Link QML debugging library check box" nor can I find a "Compile" link.
