No known conversion for argument 1 from 'Object*' to 'int*'

I'm terrible with pointers and need help passing an object to a library I'm writing. I'm getting the error no known conversion for argument 1 from 'LCDMenuItem*' to 'int*' when I try to compile. How do I pass a pointer to an object to a function?

LCDMenu.h

class LCDMenu {
    public:
    bool addItem(LCDMenuItem &item);
    private:
    LCDMenuItem *menuItems[MAX_ITEMS];
    uint8_t itemCount;
};

class LCDMenuItem {
    public:
    LCDMenuItem(char *name);
    bool setFunction(void (*function)(void));
    private:
    bool callFunction() const;
    void (*_function)(void);
    char *name;
};

LCDMenu.cpp

bool LCDMenu::addItem(LCDMenuItem &item) {
    menuItems[itemCount] = &item;
    ...
}

MySketch.ino

LCDMenuItem menuItem("Menu Option");
void setup() {
    menu.addItem(menuItem);
}

When trying to compile

bool addItem(LCDMenuItem *item);
