FindVulkan
----------
.. versionadded:: 3.7
Find Vulkan, which is a low-overhead, cross-platform 3D graphics
and computing API.
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.
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 three 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
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.
