Преобразовал проект Qt в проект VC++ - нерешенные внешние символы

Question

Почему я не могу создать и запустить проект? Я добавил необходимые .lib-файлы в свойства ввода компоновщика, добавил каталог Qt «include» в дополнительные папки ввода, скопировал файлы DLL в папку проекта и т. Д. Visual Studio все еще жалуется на нерешенные внешние символы. Что мне делать?

файл main.cpp, как так:

#include <QtWidgets/QApplication> 
#include <QtWidgets/QLabel> 

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

    QApplication app(argc, argv); 
    QLabel* label = new QLabel("Hello Qt!"); 
    label->show(); 
    return app.exec(); 
} 

Файл .pro выглядит следующим образом:

QT += core gui widgets 

TEMPLATE = app 
TARGET = hello 
INCLUDEPATH += . 

# Input 
SOURCES += main.cpp

Answer 1

Я имел чтобы преобразовать проект еще раз в проект VC++ после того, как я отредактировал файл .pro, я этого не сделал. Программа работает сейчас.
