qt extra <moduleName> doesnt work

[fire7d]

Hey, "qt extra " doesnt work for me.
After an "qt build" I did:

qt extra qtquickcontrols
qt extra qtquickcontrols2

and there's still an "Project ERROR: Unknown module(s) in QT: quick quickcontrols2". How can I verify if it's installed correctly?

Are you using cmake?

No, Im using qmake.
