Using an external class in templated method from dll - c++

Question

I'm trying to use my game engine into an external project. Everything works fine but I have a problem when I'm trying to create a custom component (That inherits from ABhaviour which is an abstract class representing a component that can be activated/disabled).
GameObject.h (exported with __declspec(dllexport))
// [...]
template <typename Class, typename ... Args>
std::shared_ptr<Class> GameObject::AddComponent(Args... args)
{
auto newComp = std::make_shared<Class>(std::forward<Args>(args)...);
m_components[typeid(*newComp).hash_code()] = newComp;
m_components[typeid(*newComp).hash_code()]->SetOwner(*this);
return newComp;
}
// [...]
In an other project (That use my game engine), I'm trying to create the custom ABehaviour :
PlayerController.h
#pragma once
#include <ElkGameEngine/Objects/Components/Behaviours/ABehaviour.h>
class PlayerController :ElkGameEngine::Objects::Components::Behaviours::ABehaviour
{
PlayerController() = default;
~PlayerController() = default;
void Update();
};
After that I add my custom component onto my "Player" GameObject :
Main.cpp
#include <ElkGameEngine/ElkGameEngine.h>
#include <ElkGameEngine/Objects/AObject.h>
#include <ElkGameEngine/Objects/Components/AComponent.h>
#include "PlayerController.h"
using namespace ElkGameEngine::Objects::Components;
using namespace ElkGameEngine::Objects::Components::Behaviours;
int main()
{
ElkGameEngine::Managers::EngineManager elkGameEngine;
elkGameEngine.GetSceneManager()->CreateScene("ElkCraft");
auto& player = elkGameEngine.GetSceneManager()->CreateEmptyGameObject("Player");
player.AddComponent<PlayerController>(); /* Here is the problem */
while (elkGameEngine.IsRunning())
{
elkGameEngine.PreUpdate();
elkGameEngine.PostUpdate();
}
return EXIT_SUCCESS;
}
Visual Studio is unhappy and print me this :

I think that the problem come from the fact that my game engine (Which is a group of DLL) is exporting a templated method (AddComponent and other ones like GetComponent).
Is it possible to use a templated method from a dll with a class/struct template argument from the project using the dll ?
Am I doing something wrong ?
Do I need to specify something on my PlayerController to make it "known/usable" in the AddComponent method ?
