 +Vulkan applications interact with Vulkan drivers through the loader.
 +
 +  * The loader is responsible for supporting multiple GPUs and their drivers.
 +  * For supporting the latest Vulkan API version, the loader also needs to be the matching version.
 +
 +More information about the loader is available here: [[https://github.com/KhronosGroup/Vulkan-Loader/blob/master/loader/LoaderAndLayerInterface.md|Vulkan Loader]]
  
 The upstream Vulkan loader source code is available in the following git repos: The upstream Vulkan loader source code is available in the following git repos:

 +==== Vulkan Validation Layers ==== 
 + 
 +The loader also supports the Vulkan validation layers, which are optional components that augment the Vulkan system. 
 + 
 +  * Layers can intercept, evaluate, and modify existing Vulkan functions on their way from the application down to the hardware. 
 +  * Layers are a critical component of developing correct Vulkan applications. 
 +  * More information about the validation layers is available here: [[https://github.com/KhronosGroup/Vulkan-ValidationLayers|Vulkan Validation Layers]]

 +</code>
 +
 +  * **CMAKE_BUILD_TYPE**:  can be **Release** or **Debug**.
 +  * **VULKAN_HEADERS_INSTALL_DIR**:  the absolute path to a Vulkan-Headers install directory must be provided.
 +  * **CMAKE_INSTALL_PREFIX**:  to customize the install location also modifies the loader search paths to include searching for layers in the specified install location.
 +    * The default value for CMAKE_INSTALL_PREFIX is /usr/local, which would be used if you do not specify CMAKE_INSTALL_PREFIX.
 +    * Setting CMAKE_INSTALL_PREFIX to /tmp/build causes the loader to search /tmp/build/etc/vulkan/explicit_layer.d and /tmp/build/share/vulkan/explicit_layer.d for the layer JSON files.
 +    * The loader also searches the "standard" system locations of /etc/vulkan/explicit_layer.d and /usr/share/vulkan/explicit_layer.d after searching the two locations under /tmp/build.
 +    * Then run make install as before, which will install the files in /tmp/build <code bash>sudo make install</code>
