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.
