You must either checkout it with GIT with all recursive submodule dependencies, or if you're using SVN (like I myself primary) you must do it manually by hand, or download all depended GIT repos (under externals/) manually by hand.
And your graphics driver of your graphics card or iGPU should must have installed the vulkan-1.dll (by including the Vulkan runtime and loader stuff from LunarG into the graphics driver setup package) otherwise it seems that your computer doesn't seems to be Vulkan-ready, at least under the Windows operating system.
