Couldn't find the examples.pri file

[Blitzor DDD]

I am using Qt Creator 4.0.3 Based on Qt 5.7.0 (GCC 4.9.1 20140922 (Red Hat 4.9.1-10), 64 bit)

and I tried to run this example: http://doc.qt.io/qt-5/qtdatavisualization-surface-example.html

but got an error: :-1: error: Couldn't find the examples.pri file! and I couldn't find in web solution of this problem..

It is like I have no such examples? How to include them painless into my system? Maybe there is an easy way to fix it.

How do you try to "run this example"?

Did you select it from the QtCreator welcome screen?
Did you open the example's .pro file in your Qt sources directory in QtCreator?

Hmm.

Maybe find it in the Qt sources of your installation and open it from there?

"examples.pri" (plural) sounds like it could be something in a parent directory of the respective example, i.e. something shared between examples.

Done, but it did not solve my problem...
