Issue with C++ file not finding included library

Question

I am working on learning C++ development and I wanted to have a file that can be used to create a window. When I run my build, it completes without an error and both CLion and Copilot have been unable to find any sort of errors. But when I run my main.cpp file, it says that my Window.cpp is unable to find the GLFW/glfw3.h file.

My CMakeLists.txt file looks like this below:

    cmake_minimum_required(VERSION 3.27)
    project(Mako)

    add_subdirectory("${CMAKE_CURRENT_SOURCE_DIR}/dependencies/glfw-3.4")
    include_directories("${CMAKE_CURRENT_SOURCE_DIR}/dependencies/glfw-3.4/include/GLFW")

    find_package(OpenGL REQUIRED)

    set(CMAKE_CXX_STANDARD 17)

    set(SOURCE_FILES main.cpp
        Window.cpp
        Window.h
    )

    add_library(Mako ${SOURCE_FILES})

    target_link_libraries(Mako glfw ${GLFW_LIBRARIES})

My code isn't anything spectacular honestly, I have a Window.cpp and Window.h file as well as a main.cpp which I'm using to test. I'm curious if I need to include the GLFW/glfw3.h file in my Window.h file but I'm not sure how to map that correctly as I am just starting to learn C++ and it's entirely reasonable I'm just being an idiot and not creating the files correctly and don't need the Window.h file and it's just causing main.cpp to become confused.

Window.cpp

    #include "Window.h"
    #include <GLFW/glfw3.h>
    #include <cstdio>

    namespace graphics
    {
        Window *Window::getInstance() { ... }
        void Window::init_window() { ... }
    }

Window.h

    
    #ifndef MAKO_WINDOW_H
    #define MAKO_WINDOW_H

    namespace graphics
    {
    class Window
    {
        Window* window;
        public:
            static Window* getInstance();
            static void init_window();
            void error_callback(int error, const char* description);
    };
    }
    
#endif //MAKO_WINDOW_H

main.cpp

    #include "Window.cpp"

    using namespace graphics;

    int main() {
        graphics::Window::init_window();
        return 0;
    }

I've tried including the GLFW/glfw3.h file in my Window.h file but ran into an issue with it not being able to find the library but the Window.cpp file is. I would expect to be able to create an instance of the Window class in main.cpp.
