Also, as a general rule of thumb, I would recommend using forward declarations in your header files. By doing so, you don’t have to include a lot of headers, which can otherwise cause a significant increase in dependencies, leading to slower build times and potential circular dependencies. Forward declarations help to keep the compilation units more independent, ultimately resulting in a more efficient build process.

Here is a simplified way to use forward declaration:

// MyClass.h
#ifndef MYCLASS_H
#define MYCLASS_H

// Forward declaration of the `OtherClass` class
class OtherClass;

class MyClass {
public:
    MyClass();
    void doSomething();

private:
    OtherClass* otherClassInstance;  // Pointer to OtherClass
};

#endif // MYCLASS_H

// MyClass.cpp
#include "MyClass.h"
#include "OtherClass.h"  // Include the full definition of OtherClass here

MyClass::MyClass() : otherClassInstance(nullptr) {}

void MyClass::doSomething() {
    // Now we have access to OtherClass' methods through the pointer
    if (otherClassInstance) {
        // Perform operations using otherClassInstance
    }
}
