Vscode可以正常运行单文件cpp程序，但无法运行多文件工程，同时输出中文也是乱码

这是launch.json文件：

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "MinGW编辑器", //可以自己定义，会在侧边栏显示
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}\\${fileBasenameNoExtension}.exe", //${fileBasenameNoExtension}表示当前打开的文件名不包括后缀
            "args": [
                "-std=c++20"
            ],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true, //false：表示调试时不弹出控制台窗口（类似dev、code blocks那种黑框）;true:弹出
            "MIMode": "gdb",
            "miDebuggerPath": "C:\\MinGW\\bin\\gdb.exe", //gdb.exe路径,windows要加.exe
            "setupCommands": [
                {
                    "description": "为 gdb 启用整齐打印",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "g++.exe build active file" //调用tasks.json，与其中的label一致
        }
    ]
}

这是tasks文件：

{
    "tasks": [
        {
            "type": "shell",
            "label": "g++.exe build active file", //与launch.json的preLaunchTask一致
            "command": "C:\\MinGW\\bin\\gdb.exe", //g++.exe的路径
            "args": [
                "-g",
                "${workspaceFolder}\\**.cpp", //${workspaceFolder}表示.vscode所在的那个文件夹的路径
                "-o",
                "${workspaceFolder}\\${fileBasenameNoExtension}.exe", //与launch的program对应
                "-std=c++17"
            ],
            "options": {
                "cwd": "${workspaceFolder}"
            },
            "problemMatcher": {
                "owner": "cpp",
                "fileLocation": [
                    "relative",
                    "${workspaceFolder}"
                ],
                "pattern": {
                    "regexp": "%(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
                    "file": 1,
                    "line": 2,
                    "column": 3,
                    "severity": 4,
                    "message": 5
                }
            },
            "group": {
                "kind": "build",
                "isDefault": true
            }
        }
    ],
    "version": "2.0.0"
}
