c++ - 如何使用任务在 Visual Studio Code 中运行 Cmake

Question

我正在尝试使用 ctrl+shift+B 运行 cmake像这样:

{
"version": "2.0.0",
"tasks": [
    {
        "label": "cmake",
        "type": "shell",
        "options": {
            "cwd": "${workspaceRoot}/build"
        },
        "command": "cmake ${workspaceRoot} -G \"MinGW Makefiles\"",
        (...)
    },
    {
        "label": "make",
        "type": "shell",
        "command": "mingw32-make.exe",
        "options": {
            "cwd": "${workspaceRoot}/build"
        },
       (...),
        "dependsOn":["cmake"]
    },
    {
        "label": "build",
        "type": "shell",
        "options": {
            "cwd": "${workspaceRoot}/build"
        },
        "group": {
            "kind": "build",
            "isDefault": true
        },
        "dependsOn": ["make"]
    }
]
}

但无论我做什么，它都运行在 ${workspaceRoot} 而不是 ${workspaceRoot}/build 上:

Executing task in folder cpppractice: cmake C:\workspace\cpp\cpppractice -G "MinGW Makefiles"

这种方法有什么问题吗？据我了解cwd options 中的变量项目应该工作。

Answer 1

{
    "label": "cmake",
    "type": "shell",
    "options": {
        "cwd": "${workspaceRoot}/build"
    },
    "command": "cmake \"MinGW Makefiles\"  ${workspaceRoot}",
},

这有效，似乎“在文件夹 cpppractice 中执行任务:”不准确并且它在正确的位置执行它，至于为什么它以前不起作用我认为它解析了错误的参数？我无法确认，但这是输出:

Executing task in folder cpppractice: cmake "MinGW Makefiles"  
C:\workspace\cpp\cpppractice <

-- Configuring done
-- Generating done
-- Build files have been written to: C:/workspace/cpp/cpppractice/build

以前它提示无法使用生成器“MinGW”，这意味着它将参数“MinGW Makefiles”分开。
经过一番修补后，我发现这也是一个答案:

{
        "label": "cmake",
        "type": "shell",
        "options": {
            "cwd": "${workspaceRoot}/build"
        },
        "command": "cmake",
        "args": [
            "-G",
            "'MinGW Makefiles'",
            "./.."
        ],
        ...
    },

我实际上发现第二种方法更简洁，但两者的工作方式相同，因此为了将参数作为字符串传递，您必须使用单引号，如下所示:

...
"command":"echo",
"args": [
        "'Za Warudo!'",
    ],
...
