Include path not working for C debugger in VSCode - Raspberry Pi

I am using VS Code remote via SSH to Raspberry Pi for my first C project. The code compiles without a problem, but the debugger can't find the header files. I have reviewed existing questions but the suggested solutions are not solving my problem.

If I place the header file in the root of my project, the file is found by the debugger.

Source, line 18:

#include "mfrc522.h"

The file is available in include folder:

tasks.json:

{
	"tasks": [
		{
			"type": "cppbuild",
			"label": "C/C++: gcc build active file",
			"command": "/usr/bin/gcc",
			"args": [
				"-fdiagnostics-color=always",
				"-g",
				"${file}",
				"-o",
				"${fileDirname}/${fileBasenameNoExtension}",
				"--include-directory=${fileDirname}/**",
				"--include-directory=${fileDirname}/include/**",
                "--include-directory=${fileDirname}/src/*/*.c",
				"--include-directory=${fileDirname}/*.c"
			],
			"options": {
				"cwd": "${fileDirname}"
			},
			"problemMatcher": [
				"$gcc"
			],

				"kind": "build",
				"isDefault": true
			},
			"detail": "Task generated by Debugger."
		}
	],
	"version": "2.0.0"
}

c_cpp_properties.json

	"configurations": [
		{
			"name": "Linux",
			"includePath": [
				"${workspaceFolder}/include/**",
				"${workspaceFolder}/**",
				"${workspaceFolder}/src",
				"${workspaceFolder}/src/*",
				"${workspaceFolder}/src/*/*.c"
			],
			"browse": {
				"path": [
					"${workspaceFolder}/include/**",
					"${workspaceFolder}/**",
				    "${workspaceFolder}/src",
				    "${workspaceFolder}/src/*",
				    "${workspaceFolder}/src/*/*.c"
				]
			},
			"defines": [],
			"compilerPath": "/usr/bin/gcc",
			"cStandard": "c17",
			"cppStandard": "gnu++14",
			"intelliSenseMode": "linux-gcc-arm64"
		}
	],
	"version": 4
}

Resulting error:
> main.c:18:10: fatal error: mfrc522.h: No such file or directory
compilation terminated.

I had not seen this answer by bko earlier, which seems to have overcome the issue of including the header files.

> What solved it for me was to just type folder path without /* or /** Then it prompted me if I want to enable Intellisense for this folder and I allowed it and it worked.
