Trying to use the SFML library

[remyk]

Hello.
I am a student beggining a project using object oriented cpp.
I never used any graphical library before therefore my knowledge in the subject is pretty limited.
I am writing a method, draw that uses a given function, buildcircle (which is defined in an external file).
What I am trying to do is, using a provided test file, to be able to draw red circles on a window where my mouse points (defined in the test file).
I use a method called addTarget to add given targets to a list of vectors called "lesCibles".
I think that I need to call my method draw while adding the targets to my list (inside addTarget) in order to have these circles drawn.
I hope that this explanation is good enough.

//addTarget method

 void Environment::addTarget(const Vec2d& cibles){

		lesCibles.push_back(cibles);
//Call the draw method ?
}



//draw method

void Environment::draw(sf::RenderTarget& targetWindow)
{
	
	for(auto lesCibles:lesCibles){
		sf::CircleShape circle = buildCircle(lesCibles, 5, sf::Color(255, 0, 0));
		targetWindow.draw(circle); //This command was given by the teacher
		}
}

//Prototype of the buildCircle funtion (external file)

sf::CircleShape buildCircle(Vec2d const& position, double radius, sf::Color color);

/*!
