Inherit Singleton

Yes there is a generic way. You can implement a Singleton via CRTP, like:

template<typename T>
class Singleton
{
protected:
    Singleton() noexcept = default;

    Singleton(const Singleton&) = delete;

    Singleton& operator=(const Singleton&) = delete;

    virtual ~Singleton() = default; // to silence base class Singleton<T> has a
    // non-virtual destructor [-Weffc++]

public:
    static T& get_instance() noexcept(std::is_nothrow_constructible<T>::value)
    {
        // Guaranteed to be destroyed.
        // Instantiated on first use.
        // Thread safe in C++11
        static T instance{};

        return instance;
    }
};

then derive from it to make your child a Singleton:

class MySingleton: public Singleton<MySingleton>
{
    // needs to be friend in order to 
    // access the private constructor/destructor
    friend class Singleton<MySingleton>; 
public:
    // Declare all public members here
private:
    MySingleton()
    {
        // Implement the constructor here
    }
    ~MySingleton()
    {
        // Implement the destructor here
    }
};
