Errors occur while compiling SFML-Imgui "undefined reference to"

Question

I'm trying to compile SFML-Imgui in the Code::Blocks application, but I get errors. I have all the necessary Imgui files in the project directory, but what else do I need to do to fix the error?

../main.cpp:13: undefined reference to `ImGui::SFML::Init(sf::RenderWindow&, bool)'

C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/12.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: ../main.cpp:22: undefined reference to `ImGui::SFML::ProcessEvent(sf::Event const&)'

Code:

#include <SFML/Graphics.hpp>

#include <imgui.h>

using namespace std;
using namespace sf;

int main()
{
    sf::RenderWindow window(sf::VideoMode(800, 800), "Test");
    ImGui::SFML::Init(window);
    sf::Clock dClock;
    while (window.isOpen()){
        sf::Event event;
        while (window.pollEvent(event))
        {
            ImGui::SFML::ProcessEvent(event);
            if (event.type == sf::Event::Closed)
                window.close();
        }
        ImGui::SFML::Update(window, dClock.restart());
        window.clear();
        sf::CircleShape shape(100);
        shape.setFillColor(sf::Color::Green);
        window.draw(shape);
        ImGui::SFML::Render(window);
        window.display();
    }

    ImGui::SFML::Shutdown();
    return 0;
}
