QT Debug information files, where?

[Josko]

Hello!

When trying to compile an OpenCV dependent app in DEBUG mode (under Windows and MSVC 2017 compiler), I get complaint from QT that "QT Debug information files" are missing and that they are supposed to be installed through Maintenance Tool. But when opening Maintenance Tool I can't see anything similar to this what hasn't already been checked?
Thanks in advance!!

@Josko Those debug files are only needed to debug Qt itself. You do not need them to build your app in debug mode.

Guys, can you elaborate on the solution to this problem?

@jsulm , can you elaborate on the solution to this problem?

@pai_daxing : You do need debug info for Qt only if you want to debug inside Qt. This is sometimes convenient to do also for debugging of client code, but not a strict need.

You can simply press "Ok" (or select Do not show again first) here.

There is nothing to elaborate on. As @jsulm wrote at the time
