# ----------

#

# 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
|
||||||
