tasks.json for SDL helloWorld app on Mac with Visual Studio Code

I'm trying to learn how to use SDL on Mac, I have a working example running from command line with this structure :

 include (directory with the SDL include folder)
 lib (directory with the SDL lib folder)
 main.cpp
 makeFile

The content of my makefile is the following:

game:
    g++ main.cpp -o play -I include -L lib -l SDL2

As I have already mentioned everything works. Now I would like to use the Visual Studio Code and configure the project so I have create a tasks.json like the following:

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558 
    // for the documentation about the tasks.json format

        "version": "2.0.0",
        "tasks": [
            {
                "label": "build",
                "command": "g++",
                "args": [
                    "main.cpp", // main file
                    "-o",
                    "play", // executable
                    "-I include",
                    "-L lib", 
                    "-l SDL2"
                ],
                "type": "shell",
                "presentation": {
                    "echo": true,
                    "reveal": "always",
                    "panel": "shared"
                },
                "problemMatcher": {
                    "owner": "cpp",
                    "fileLocation": [
                        "relative",
                        "${workspaceRoot}"
                    ],
                    "pattern": {
                        "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
                        "file": 1,
                        "line": 2,
                        "column": 3,
                        "severity": 4,
                        "message": 5
                    }
                }
            }
        ]
    }

But I'm getting the following error:

> Executing task: g++ main.cpp -o play '-I include''-L lib''-l SDL2'<

ld: warning: directory not found for option '-L lib'
ld: library not found for -l SDL2
clang: error: linker command failed with exit code 1 (use -v to see invocation)
The terminal process terminated with exit code: 1

Terminal will be reused by tasks, press any key to close it.

Do you have any idea about what can be the problem?
