Example doesn't work if Qt installed read-only

Installed QT in /opt/Qt. Opened Qt Creator from the toolbar. Tried to open example Qt Quick Gallery. It pops up a dialog box asking whether I wanted to copy the example to a writable location. I answer in the affirmative and provide a location.

It does copy the example, but the example .pro contains a relative file path to ../shared that is not copied from /opt/Qt. The example doesn't build with an odd error that the Kit isn't configured. I tried copying it manually but that didn't resolve the issue.
