I am writing a QML Ubuntu Application and unfortunately forgot to check the boxes for the different Device Kits when I created the Project.
How do I get those Device Kits to show up at the run menu?
With your project opened in Qt Creator, select the Projects tab on the left-hand side. This will give you several tabs across the top. Build & Run should already be selected. Just under this there is an Add Kit button. Click it, and a list of kits you can add to the current project will drop down. Select the one you want to add, and you should be all set.
