即使使用 ifndef，C++ 重定义错误

我有几个文件，我的错误很奇怪。我不知道这是否可能是问题的一部分，我使用OpenGL/SDL，XCode，并使用CMake创建文件。

我有文件Wall.hpp，Wall.cpp，Player.hpp，Player

.cpp，controls.hpp，controls.cpp，main.cpp。

以下是文件包含的摘要：

播放器.hpp

#include <iostream>

class Player{
    public :
    Player();
    int getLifePoints();
    int getStaminaPoints();
    float getPosX();
    float getPosY();
    float getPosZ();
    void setPosX(float x);
    void setPosY(float y);
    void setPosZ(float z);
    void reducePoints(int damage);
    bool isHeroRunning();
    void changeHeroRun();
    bool isHeroDucking();
    void changeHeroDuck();

    private :
    int lifePoints;
    int staminaPoints;
    float posX;
    float posY;
    float posZ;
    bool isRunning;
    bool isDucking;

代码运行良好，直到我将 #include"Wall.hpp"放入文件控件.hpp或/和控件中.cpp。我正面临错误"重新定义墙"，以及在此之后"Gl.h 包含在 glew.h 之前"。
