I want to use <format> lib in my program to format the output

#include <format>

// matrix display
template<typename T>
void algebra::display(const algebra::MATRIX<T> &matrix) {
    for (const auto& row : matrix) {
        std::cout << "|";
        for (const auto& elem : row) {
            std::cout << std::format("{:^7}", elem) << "|";
        }
        std::cout << "n";
    }
}

However, the compiler throws an error:

fatal error: format: No such file or directory
11 | #include
| ^~~~~~~~
compilation terminated.

I have set the c++ version in the CMakeLists.txt:

# Specify the minimum required version of CMake for this project. 
cmake_minimum_required(VERSION 3.14)

project(AUT_AP_2024_SPRING_HW1)
set(CMAKE_CXX_STANDARD 23)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

And I have checked the version of gcc, it is satisfied the requirement for <format>.
