Visual Studio CMake Presets添加option

Posted on Edited on In Disqus: Word count in article: 2.3k Reading time ≈ 2 mins.

今天试了试用Visual Studio打开Qt的CMake项目，但是VS里用CMake的方式好像和Qt Creator的不一样。

因为我的项目CMake里有一个自定义的option，在Qt的项目设置里有GUI可以设置那个option，但是在VS里找了一会没找到，而且VS好像是用cmake presets来设置的，于是问了一下Copilot。 简单来说就是在cacheVariables里加上要设置的option就行了，我这里是BUILD_EXAMPLE。

之后还是得抽空学一学CMake。

以下是copilot的回答。 Certainly! To modify the CMakePresets.json file and set the "BUILD_EXAMPLE" option to true, follow these steps:

  1. Open the CMakePresets.json file in a text editor.

  2. Locate the appropriate configure preset where you want to set the "BUILD_EXAMPLE" option. In your provided example, we have two presets: "Qt-Debug" and "Qt-Release".

  3. Add or modify the "cacheVariables" section within the chosen configure preset. Specifically, add an entry for "BUILD_EXAMPLE" with the value "ON" (to set it to true). For example:

    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11
    12
    13
    {
      "name": "Qt-Debug",
      "inherits": "Qt-Default",
      "binaryDir": "${sourceDir}/out/build",
      "cacheVariables": {
        "CMAKE_BUILD_TYPE": "Debug",
        "CMAKE_CXX_FLAGS": "-DQT_QML_DEBUG",
        "BUILD_EXAMPLE": "ON"  // Add this line
      },
      "environment": {
        "QML_DEBUG_ARGS": "-qmljsdebugger=file:{908eb81f-69af-44f1-b571-199332c0b484},block"
      }
    }

  4. Save the modified CMakePresets.json file.

Remember that CMakePresets.json specifies project-wide build details, so any changes you make here will affect the entire project. If you want to customize your local build details, consider using CMakeUserPresets.json instead⁴. Make sure to follow best practices for version control, such as ignoring CMakeUserPresets.json if you're using Git.

Feel free to adjust other settings in the presets as needed for your project! 😊
