c++ - 在 Visual Studio 2019 中使用 Qt 时出错

Question

我正在尝试在 Visual Studio 2019 中使用 Qt。我在 VS 中安装了扩展“Qt VS 工具”并添加了我的 Qt 路径。我在 VS 中创建了一个新的 Qt Gui 应用程序项目。没有更改任何内容，我收到错误

  == Qt Visual Studio Tools version 2.4.2

   Initialized in: 14169,6 msecs
   Main (UI) thread: 292,38 msecs

TestQT.vcxproj: background build FAILED!
TestQT.vcxproj: background build FAILED!
TestQT.vcxproj: background build FAILED!

作为 Qt VS 工具的输出，如果我尝试构建这个项目，我会得到

我对这个新手问题感到抱歉，但我现在在谷歌上搜索了几个小时......
