我正在尝试编译一个C++程序“test.cpp”，其中包含一个使用VS Code的自定义文件“Cars. h”。然而，它导致了一个构建错误，即使我很确定我做的一切都是正确的。
我的目录结构：

Test
├── .vscode
│   ├── tasks.json
├── include
│   ├── Cars.cpp
│   └── Cars.h
├── test.cpp

test.cpp

#include <iostream>
#include "include/Cars.h"

using namespace std;

int main(){
    Cars c;
    cout << "Hello!" << endl;
    c.printcars();  
}

Cars.cpp

#include <iostream>

class Cars{

    public:
        void printcars(){
            std::cout << "Cars" << std::endl;
        }

};

Cars.h

#ifndef CARS_H
#define CARS_H

class Cars {
    public:
        void printcars();

};

#endif

tasks.json

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "cppbuild",
            "label": "buildFile",
            "command": "g++",
            "args": [
                "-o",
                "${fileBasenameNoExtension}.exe",
                "${file}",
                "${workspaceFolder}\\include\\*.cpp",
                "${workspaceFolder}\\include\\*.h",
                "-I${workspaceFolder}\\include"
            ],
            "options": {
                "cwd": "${workspaceFolder}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": "build"
        }
        
    ]
}

错误：

test.cpp:(.text+0x37): undefined reference to `Cars::printcars()'
collect2.exe: error: ld returned 1 exit status

Build finished with error(s).

 *  The terminal process terminated with exit code: -1. 
 *  Terminal will be reused by tasks, press any key to close it.

我确信这是一个链接器错误，因为当我包含Cars.cpp而不是Cars.h时，程序运行得很好。然而，这是一个测试，我需要包括头文件只。
