How to make an object to look at Raycast Hit Point?

Question

I raycasted a ray and stored its collision point data in hitTarget var. I tried to make the object look at this point by LookAt(hitTarget) but it seems that the parameter inside LookAt() must be a Transform variable. I also tried to create an empty object at the hitTarget position and change its position every frame to match the new hitTarget position but I can't make my object(e.g Turret) to look at this empty. How can I achieve that, which is making the object I want to look at the hit point position?

RaycastHit.point returns a vector3. Ref

transform.LookAt can take a Transform or a Vector3. It will point the Z axis of your object in that direction. Ref

So if you just need some object to look at the hit point of some ray then you could do something like this.

 using UnityEngine;
 using System.Collections;
 
 public class example : MonoBehaviour {
     public Transform turret;
     void Update() {
         RaycastHit hit;
         if (Physics.Raycast(transform.position, Vector3.forward, out hit)){
              Vector3 hitPosition = hit.point;
              turret.LookAt(hitPosition);
         }
         
     }
 }

And to fix it up to look at a Transform (as the OP was thinking,) use hitTarget.transform
