title: Vulkan demo does not compile on Nvidia Jetson TX2
body: <p>I have downloaded the Vulkan SDK from LunarG here: </p>
  
  <p><a href="https://github.com/LunarG/VulkanTools/" rel="nofollow noreferrer">https://github.com/LunarG/VulkanTools/</a></p>
  
  <p>I have compiled it successfully using the instructions in BUILDvt.md and have a "vulkan" directory which has the vulkan.h and vulkan.hpp files. I have copied this entire vulkan directory tino /usr/local/include so that gcc can find it. </p>
  
  <p>However when I go to the demos directory in my VulkanTools and type gcc cube.h I get this:</p>
