if application wan to use the third party library that using from engine, the third party library will need to export themself as a dll file so application can use it.

Example:

Application want to use ImGui but it only link staticly with the Engine itself

solution: export imgui as dll to engine dll-> export engine dll to the application

this allow us to solve the linking problem and use the functionality from the application

///Note now the engine is not dll anymore, it is staticlib instead
