#### System Information
- Ogre Version: v14.4.1
- Operating System / Platform: Windows 11 / ARM64
- RenderSystem: NA

#### Detailled description
When configuring ogre on ARM64 on Windows I'm hitting linking errors about unresolved `_Interlocked*` symbols in SDL2. E.g.:

`SDL_malloc.c.obj : error LNK2001: unresolved external symbol _InterlockedCompareExchange`

They are caused by an [issue in SDL](https://github.com/libsdl-org/SDL/issues/13254) that has been fixed in the most recent version. I'll put up a PR soon to upgrade SDL.
