Can’t create plain C++ project in Qt creator - no valid kits found

Question

This is a question about Qt Creator 2.8.0. When I go to

File>>New File or Project>>Non-Qt Project>>Plain C++ Project

Then I get to this page. When I press “Next” then I get to this page and get the error:

No valid kits found

I can’t press “Next”. I can click on "options" which takes me to this page. I am using the latest version of Qt creator (2.8.0) installed on fully updated Fedora 19 64bit. What is a kit and how can I add it so that I can create plain C++ project?

Solution

I have just solved it. I had to change “Qt version” from “None” to “Qt 4.8.5 in PATH (System)”. Now the kit shows correctly.
