This is largely an unfortunate packaging issue on Windows where the CMake infrastructure for Vulkan expects to find the Vulkan headers (which we don't need), as well as the Vulkan loader library (which is needed for linking), all of which are packaged up in the SDK. So installing the SDK is the easiest solution, but not ideal and creates another dependency that we don't need.

Unfortunately, this may mean adding a custom CMake FindVulkan method that simply locates the path to the loader library to configure a proper environment for AOT tests and apps.
