Debug for multiple C++ files in VSCode

Question

I think i entered all of the correct settings but it gave me a prelaunch task error because the program contains multiple files so i tried to correct the tasks.json settings and set args to "*.cpp" but i still have the same problem.
Note that all the files are in the same folder and that i have no errors during the compilation.

Prelaunch task error :

After setting "*.cpp" in the args in tasks.json i still get the previous error + this :

launch.json settings :

This is my sample settings

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/api.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}/",
            "environment": [],
            "preLaunchTask": "build",
            "externalConsole": true,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "g++",
            "args": [
                "-Wall",
                "-o",
                "api.exe",
                "*.cpp"
            ]
        }
    ]
}
