Why can Visual Studio 2019 not find the Qt include-files?

I'm using the project wizard and am receiving the following error messages:

E1696 cannot open source file "QtWidgets/QApplication"

E1696 cannot open source file "QtWidgets/QMainWindow"

I added the include-files under Project -> Properties... -> Configuration Properties -> C/C++ -> General -> Additional Include Directories

as

D:\Qt\Qt5.14.0\5.14.0\msvc2017\include

That is, Visual Studio 2019 resides on C:, while Qt does on D:.

I controlled the actions of Visual Studio 2019 via Process Monitor, and it never showed an attempt to even access a Qt-directory, not to speak of the include file itself (protocol added).

Any ideas on this one?

Project files.

Process Monitor log.

I have had problems previously with VS19 and the Qt include files. The solution to my problem was that I had to first open VS19 (by itself), then select the "Open a project or solution" from the start page.
