Windows 7, Qt creator(4.5.0), oF(0.10.0), no ofMain.h file

I created a new openframework project in Qt creator following, but the ofMain.h can’t be found. And I also can’t find ofMain.h in the oF dir. The .qbs files are gray.

Any advice on how to solve this issue would be greatly appreciated.
All best.

I solved this problem by changing kits to MSCV2017 64bit.
But a new problem has arisen.

How to solve this problem?

When I performed the below step, I solved all the problems.
