C++: произошло несколько определений [дубликат] ⇐ C++

Прежде всего, извините за мой плохой английский.
Поэтому, когда я пытаюсь запустить свой проект, я получаю эту ошибку.

и я не понимаю, откуда я взял эти многочисленные определения и почему. Файлы моего проекта, в которых упоминаются текстуры, выглядят следующим образом:
main.cpp:

#include "Game.h"

int main()
{
Game game;
Textures::setTextures();
Player* player = new Player(Textures::player_texture, sf::Vector2f(PLAYER_START_X,PLAYER_START_Y),PLAYER_START_HP);
sf::Clock clock;

while(game.Runing()){
float time = clock.getElapsedTime().asMicroseconds();
clock.restart();
time/=300;
game.Update();
player->Update(time);
game.Render(player);
}
delete player;
return 0;
}

if (m_state == State::RUN) {

}
else {

}

m_sprite.setPosition(m_pos);

void Player::setState(State state) {
m_state = state;
}

и мои CmakeLists выглядят так:

find_package(SFML 2.5 REQUIRED graphics network audio window system)

Я пытался использовать extern для sf::Texture player_texture, это исправило несколько определений, но вызвало это

Надеюсь, кто-нибудь из вас сможет мне помочь
