This fork has updated the layer to use a more modern library, and builds without modification, using the same dependencies.

Hello, there were some changes to the Vulkan-ValidationLayers upstream moving the headder files to Vulkan-Utility-Libraries. I created a patch that makes it work with the changes and I've created a Github repository where I added those changes.

I created a gist for this patch as it's a bit longer and I don't want to post such a long comment here.

This no longer builds. The vulkan_layer_dispatch.h file has been moved so it's under vulkan/generated/vk_layer_dispatch_table.h now. A patch needs to be applied to get this building again. The contents of the vulkan-headers.patch file I used are below:

The version also needs to be bumped otherwise vulkan complains. version.patch:
