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.
There are corresponding imported targets for each of these.

``glslc``
  The SPIR-V compiler.

``glslangValidator``
  The ``glslangValidator`` tool.

``glslang``
  The SPIR-V generator library.

``shaderc_combined``
  The static library for Vulkan shader compilation.

``SPIRV-Tools``
  Tools to process SPIR-V modules.

``MoltenVK``
  On macOS, an additional component ``MoltenVK`` is available.

``dxc``
  .. versionadded:: 3.25

  The DirectX Shader Compiler.

The ``glslc`` and ``glslangValidator`` components are provided even
if not explicitly requested (for backward compatibility).

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).

``Vulkan::MoltenVK``
  .. versionadded:: 3.24

  Defined if SDK has the Khronos library which implement a subset of Vulkan API
  over Apple Metal graphics framework. (MoltenVK).

``Vulkan::volk``
  .. versionadded:: 3.25

  Defined if SDK has the Vulkan meta-loader (volk).

``Vulkan::dxc_lib``
  .. versionadded:: 3.25

  Defined if SDK has the DirectX shader compiler library.

``Vulkan::dxc_exe``
  .. versionadded:: 3.25

  Defined if SDK has the DirectX shader compiler CLI tool.

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_glslc_FOUND``
  .. versionadded:: 3.24

  True, if the SDK has the glslc executable.
``Vulkan_glslangValidator_FOUND``
  .. versionadded:: 3.24

  True, if the SDK has the glslangValidator executable.
``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.
``Vulkan_MoltenVK_FOUND``
  .. versionadded:: 3.24

  True, if the SDK has the MoltenVK library.
``Vulkan_volk_FOUND``
  .. versionadded:: 3.25

  True, if the SDK has the volk library.

``Vulkan_dxc_lib_FOUND``
  .. versionadded:: 3.25

  True, if the SDK has the DirectX shader compiler library.

``Vulkan_dxc_exe_FOUND``
  .. versionadded:: 3.25

  True, if the SDK has the DirectX shader compiler CLI tool.


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.
``Vulkan_MoltenVK_LIBRARY``
  .. versionadded:: 3.24

  Path to the MoltenVK library.

``Vulkan_volk_LIBRARY``
  .. versionadded:: 3.25

  Path to the volk library.

``Vulkan_dxc_LIBRARY``
  .. versionadded:: 3.25

  Path to the DirectX shader compiler library.

``Vulkan_dxc_EXECUTABLE``
  .. versionadded:: 3.25

  Path to the DirectX shader compiler CLI tool.

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.
