General / CMake include problem

« on: June 10, 2021, 09:06:35 pm »

Hello. Working on Windows. Im trying to dive in gamedev, but this thing is blocking me.
Im trying to include "SFML/Graphics.hpp" in one of my header files, located in src folder. Main.cpp is located in the same directory.

#pragma once

#include <SFML/Graphics.hpp>

class Window
{
public:
    Window(const std::string& window_name);

    void update();

    void beginDraw();
    void Draw(const sf::Drawable& drawable);
    void endDraw();

    bool isOpen() const;

private:
    sf::RenderWindow window;
}
 

This is the trouble header. When compiling it says that it cant find SFML/Graphics.

CMakeLists.txt, located out of src folder.

cmake_minimum_required(VERSION 3.20.3)

project(SNAKE)

add_subdirectory(src)


set(SFML_DIR "c:\\SFML\\lib\\cmake\\SFML\\")
find_package(SFML 2.5 COMPONENTS graphics audio REQUIRED)
target_link_libraries(${PROJECT_NAME} sfml-graphics sfml-audio)
 

window.hpp is located in src folder. CMakeLists.txt in src folder:

add_executable(${PROJECT_NAME} main.cpp)


add_library(window window.cpp window.hpp)


set(LIBRARIES window)
target_link_libraries(${PROJECT_NAME} ${LIBRARIES})
 

Error log:

In file included from E:\GameDev\SFML\Snake\src\window.cpp:1:
E:\GameDev\SFML\Snake\src\window.hpp:3:10: fatal error: SFML/Graphics.hpp: No such file or directory
 #include <SFML/Graphics.hpp>
 

Whats interesting, main.cpp located in the same directory has no trouble including "SFML/Graphics".
Im new to cmake and dont know how things work. Can someone help me to make "window.hpp" include "SFML/Graphics.hpp" correctly?
