对"_imp___ZN12QApplicationC1ERiPPci"的未定义引用

我正在使用CodeBlocks。 如果需要，这是项目：https://i.stack.imgur.com/H6Iyi.png

我是C++非常早期的初学者，我一直在检查RPG游戏（TTU供参考）代码的启动器，试图修复并运行它。 我遇到了一堆我可以轻松修复的错误，但我遇到了这个障碍，我不确定问题是什么。 我想我必须在项目设置中添加Qt的库？但是我不知道在哪里可以找到这些库文件以及要链接哪些文件等。 这是收到以下错误的文件 （core\main.cpp）：

#include "uiLauncherWindow.h"
#include <QtWidgetsQApplication>
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    LauncherWindow *launcher_window = new LauncherWindow;
    launcher_window->show();
    return app.exec();
}

我收到这些错误：

那么有人可以解释一下问题到底是什么，以及如何解决它吗？ 提前非常感谢你。-英托沙多:)
