According to dependency scanner it depends on Qt6Qml.dll, Qt6Core.dll
and World.dll. All of these should be either be available from Qt or
from the additional import path I provided. Even when copying the dlls
into the directory, I get the same error.

The Hello class contains just a single function:
#pragma once
#include <QObject>
#include <QQmlEngine>
#include <QDebug>
class Hello : public QObject {
Q_OBJECT
QML_ELEMENT
public slots:
void speak();
};
*and my test qml:*
import QtQuick
import QtQuick.Layouts
import QtQuick.Controls
import QtQuick.Controls.Material
import Hello.World 1.0

On windows, you have to jump through some hoops to make it find the
backing library. There is PATH. You can install the backing library in
some place that's already on your PATH or you can adapt PATH. If you
have a custom executable you can also install the backing library next
to it.
