CMake/VS2019: Specified module could not be found

Jhalter2

I'm using Qt in VS2019 which I have built with CMake. When I run my application I get the error

"QQmlApplicationEngine failed to load component
qrc:/main.qml:1:1: Cannot load library C:\Qt62\6.2.1\msvc2019_64\qml\QtQuick\qtquick2plugind.dll: The specified module could not be found."

I have the file at the location specified (my Qt install folder). I've stripped down my code to the bare minimum needed to reproduce this error. My Qml file just cannot seem to import modules. I've specified the import path in my C++ code and also added the qml module in my CMake.

CMake Code:

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_AUTOUIC ON)

qt_import_plugins(TouchpadExperiment QWindowsIntegrationPlugin)

    Qt6 6.2 COMPONENTS 
        Core
        Quick
        Gui
        Qml
        GuiTools
        CoreTools
        QmlTools
    REQUIRED
)

qt_add_executable(TouchpadExperiment
    main.cpp
    resources.qrc

qt_add_qml_module(TouchpadExperiment

)

target_link_libraries(TouchpadExperiment PRIVATE
    Qt6::Core
    Qt6::Gui 
    Qt6::Quick
    Qt6::Qml
)

C++ code:

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QQuickWindow>

int main(int argc, char *argv[])
{
  QGuiApplication app(argc, argv);

  QQmlApplicationEngine engine;
  engine.addImportPath("C:/Qt62/6.2.1/msvc2019_64");
  engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
}

QML Code:

import QtQuick 

Window {
}

@Jhalter2 said in CMake/VS2019: Specified module could not be found:

C:\Qt62\6.2.1\msvc2019_64\qml\QtQuick\qtquick2plugind.dll

Does this file exist on disk?

The *d.dll implies a Debug build. Does it work better if you do a Release build?

@Crisian-Adam-0 I have verified that the file does exist at that location. I receive the same errors when attempting to run in Release mode.
