Missing DLL file: UnsatisfiedLinkError: tier4_simulation_msgs__rosidl_typesupport_c.dll

[samanipour]

Describe the bug Hi, @adamdbrw @pijaro if you could help me to solve this issue I would be very appreciated

I'm trying to setup AWSIM-Lab as Unity Project on Windows. Following this issue we found out that ros2-for-unity has missing library file when we try to run it under Windows 11 and AWSIM-Lab as Unity Project setup.

To Reproduce Steps to reproduce the behavior:

1. Follow AWSIM-Lab Setup Instructions for Windows
2. Run the demo in Unity Editor
3. Open Unity Console
4. See error UnsatisfiedLinkError: tier4_simulation_msgs__rosidl_typesupport_c.dll ROS2.DllLoadUtilsWindowsDesktop.ROS2.DllLoadUtils.LoadLibraryNoSuffix (System.String fileName) (at <c2fd60e12ae74b49b3633ef9563fbe65>:0) tier4_simulation_msgs.msg.DummyObject..cctor () (at <875a1a567ccc4ffe8e2115395ef84ff7>:0) Rethrow as TypeInitializationException: The type initializer for 'tier4_simulation_msgs.msg.DummyObject' threw an exception.
