When using vscode with cmake, a cmake error occurs

I'm using vscode with cmake for debug on a windows system, but task.json executes to the cmake command with this error:

`Executing task: D:\Cmake\bin\cmake.exe .. -G 'MinGW Makefiles' 

CMake Error: Could not create named generator 'MinGW Makefiles'`

Here is the command for cmake in my task.json file:

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

How exactly should I write the args -G MinGW Makefiles?
