FindVulkan
----------
Find Vulkan, which is a low-overhead, cross-platform 3D graphics
and computing API.
IMPORTED Targets
^^^^^^^^^^^^^^^^
This module defines :prop_tgt:`IMPORTED` target ``Vulkan::Vulkan``, if
Vulkan has been found.
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables::
Vulkan_FOUND - "True" if Vulkan was found
Vulkan_INCLUDE_DIRS - include directories for Vulkan
Vulkan_LIBRARIES - link against this library to use Vulkan
The module will also define two cache variables::
Vulkan_INCLUDE_DIR - the Vulkan include directory
Vulkan_LIBRARY - the path to the Vulkan library
