FindVulkan
----------

.. versionadded:: 3.7

Find Vulkan, which is a low-overhead, cross-platform 3D graphics
and computing API.

Optional COMPONENTS
^^^^^^^^^^^^^^^^^^^

.. versionadded:: 3.24

This module respects several optional COMPONENTS: ``glslang`` ``shaderc_combined`` and
``SPIRV-Tools``.  There are corresponding import targets for each of these
flags.

IMPORTED Targets
^^^^^^^^^^^^^^^^

This module defines :prop_tgt:`IMPORTED` targets if Vulkan has been found:

``Vulkan::Vulkan``
  The main Vulkan library.

``Vulkan::glslc``
  .. versionadded:: 3.19

  The GLSLC SPIR-V compiler, if it has been found.

``Vulkan::Headers``
  .. versionadded:: 3.21

  Provides just Vulkan headers include paths, if found.  No library is
  included in this target.  This can be useful for applications that
  load Vulkan library dynamically.

``Vulkan::glslangValidator``
  .. versionadded:: 3.21

  The glslangValidator tool, if found.  It is used to compile GLSL and
  HLSL shaders into SPIR-V.

``Vulkan::glslang``
  .. versionadded:: 3.24

  Defined if SDK has the Khronos-reference front-end shader parser and SPIR-V
  generator library (glslang).

``Vulkan::shaderc_combined``
  .. versionadded:: 3.24

  Defined if SDK has the Google static library for Vulkan shader compilation
  (shaderc_combined).

``Vulkan::SPIRV-Tools``
  .. versionadded:: 3.24

  Defined if SDK has the Khronos library to process SPIR-V modules
  (SPIRV-Tools).

Result Variables
^^^^^^^^^^^^^^^^

This module defines the following variables:

``Vulkan_FOUND``
  set to true if Vulkan was found
``Vulkan_INCLUDE_DIRS``
  include directories for Vulkan
``Vulkan_LIBRARIES``
  link against this library to use Vulkan
``Vulkan_VERSION``
  .. versionadded:: 3.23

  value from ``vulkan/vulkan_core.h``
``Vulkan_glslang_FOUND``
  .. versionadded:: 3.24

  True, if the SDK has the glslang library.
``Vulkan_shaderc_combined_FOUND``
  .. versionadded:: 3.24

  True, if the SDK has the shaderc_combined library.
``Vulkan_SPIRV-Tools_FOUND``
  .. versionadded:: 3.24

  True, if the SDK has the SPIRV-Tools library.

The module will also defines these cache variables:

``Vulkan_INCLUDE_DIR``
  the Vulkan include directory
``Vulkan_LIBRARY``
  the path to the Vulkan library
``Vulkan_GLSLC_EXECUTABLE``
  the path to the GLSL SPIR-V compiler
``Vulkan_GLSLANG_VALIDATOR_EXECUTABLE``
  the path to the glslangValidator tool
``Vulkan_glslang_LIBRARY``
  .. versionadded:: 3.24

  Path to the glslang library.
``Vulkan_shaderc_combined_LIBRARY``
  .. versionadded:: 3.24

  Path to the shaderc_combined library.
``Vulkan_SPIRV-Tools_LIBRARY``
  .. versionadded:: 3.24

  Path to the SPIRV-Tools library.

Hints
^^^^^

.. versionadded:: 3.18

The ``VULKAN_SDK`` environment variable optionally specifies the
location of the Vulkan SDK root directory for the given
architecture. It is typically set by sourcing the toplevel
``setup-env.sh`` script of the Vulkan SDK directory into the shell
environment.
