-# FindVulkan
-# ----------
-#
-# Try to find Vulkan
-#
-# 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
-#
