title: How do you install the Vulkan validation layers on Windows?
body: <p>I am following the instructions on the Vulkan-LoaderAndValidationLayers github:
  <a href="https://github.com/KhronosGroup/Vulkan-LoaderAndValidationLayers/blob/master/layers/README.md" rel="nofollow noreferrer">https://github.com/KhronosGroup/Vulkan-LoaderAndValidationLayers/blob/master/layers/README.md</a></p>
  
  <p>I've built the layers, copied the DLLs next to my executable (for test purposes, will setup the path later), created a vk_layer_settings.txt (also alongside my executable), and set the layer names in my VK_INSTANCE_LAYERS env. var. </p>
  
  <p>But no matter what I do the array returned by vkEnumerateInstanceLayerProperties does not contain any validation layers.</p>
  
  <p>What magic step have I missed? This is Windows 8.1 running on a Nvidia 970M</p>
