It might be worth considering deprecating Vulkan::Registry entirely though due to this awkward difference between the add_subdirectory / find_package use scenario...

[juan-lunarg]

For clarification the validation layers consume Vulkan-Headers via find_package.

Which produces VulkanHeadersConfig.cmake

Which contains this line:

# Create imported target Vulkan::Registry
add_library(Vulkan::Registry INTERFACE IMPORTED)

set_target_properties(Vulkan::Registry PROPERTIES
  INTERFACE_INCLUDE_DIRECTORIES "${_IMPORT_PREFIX}/share/vulkan/registry"
)

I'm not sure how your build even got passed this line in VVL:

find_package(VulkanHeaders REQUIRED CONFIG QUIET)

FWIW package managers like Conan/vcpkg help avoid this scenario entirely.

I sure many users use Vulkan* libraries via git submodules + add_subdirectory.
