使用Visual Studio运行Qt CMake个项目

Question

I'm using Visual Studio 2019 to build a CMake project that uses Qt. Visual Studio natively supports CMake, so integrating it with Qt I just modified the CMakeSettings.json file by adding a globa variable as follows:

      "variables": [
        {
          "name": "CMAKE_PREFIX_PATH",
          "value": "path_to_qt_installation",
          "type": "STRING"
        }
      ]

This directs CMake to correctly find the Qt libraries and builds the project successfully. However when trying to run the project, Visual Studio cannot find the Qt dll and link them to the executable:

The code execution cannot proceed because Qt5Qml.dll was not found. Reinstalling the program may fix this problem.

To solve this problem, I can manually run windeployqt.exe inside the build directory and then run the program. This solves the issue, however I would like to avoid this and would like Visual Studio to find the Qt dll files automatically. Qt Creator on Windows does this by default, so I would like the same experience with VS 2019. What is the correct to solve this issue?

Answer 1

If the DLL is not in the same folder as the executable, Windows will search for the file in the folder specified in the system path.
