CMake Static Linking SFML Libraries [undefined reference]

[Kas_st]

For a project im trying to statically link the sfml libraries.
I've built the sfml libraries from source with the same compiler im trying to build the project with.
The samples are all working correctly.
Now I'm trying to link my project using CMake, for reference im using Visual Studio Code as my editor:

HelloWorld.cpp:

#include "SFML/Graphics.hpp"

int main()
{
    sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Green);

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear();
        window.draw(shape);
        window.display();
    }

    return 0;
}

So pretty much only linking errors. I've checked that I link all the dependencies of the sfml libraries that im using (graphics) found on: https://www.sfml-dev.org/tutorials/2.5/start-cb.php


Am I missing something crucial in the linking process?

The get_target_property call in CMakeLists returns the correct paths to the libraries that should be linked and I've verified that all of the system32 dlls exist.

Thanks in advace!

You CMake code isn't how you find SFML.

Like mentioned in this thread you really just need to have the following three statements for linking SFML statically:

set(SFML_STATIC_LIBRARIES TRUE)
find_package(SFML 2.5 COMPONENTS graphics audio REQUIRED)
...
target_link_libraries(SFMLTest sfml-graphics sfml-audio)

This requires that you set SFML_DIR to the directory where the SFML config files are located (usually SFML/lib/cmake/SFML).

Note also that SFML will automatically look for its dependencies and link them, so you don't really need to search for freetype in your own CMake script.
