FindVulkan

Added in version 3.7.

Finds Vulkan, a low-overhead, cross-platform 3D graphics and computing API, along with related development tools typically provided by the Vulkan SDK:

find_package(Vulkan [<version>] [COMPONENTS <components>...] [...])

Vulkan includes commonly used utilities such as shader compilers and SPIR-V tools (e.g., DXC, glslc, glslang, etc.) that support Vulkan-based development workflows.

Components

Added in version 3.24.

This module supports several optional components that can be specified with the find_package() command:

find_package(Vulkan [COMPONENTS <components>...])

Each component provides a corresponding imported target. Supported components include:

glslc

Added in version 3.24.

Finds the SPIR-V compiler. This optional component is always implied automatically for backward compatibility, even if not requested.

glslangValidator

Added in version 3.24.

Finds the glslangValidator tool that is used to compile GLSL and HLSL shaders into SPIR-V. This optional component is always implied automatically for backward compatibility, even if not requested.

glslang

Added in version 3.24.

Finds the Khronos-reference front-end shader parser and SPIR-V code generation library (glslang).

shaderc_combined

Added in version 3.24.

Finds the Google static library used for Vulkan shader compilation.

SPIRV-Tools

Added in version 3.24.

Finds Khronos library for analyzing and transforming SPIR-V modules.

MoltenVK

Added in version 3.24.

Finds the Khronos MoltenVK library, which is available on macOS, and implements a subset of Vulkan API over Apple Metal graphics framework.

dxc

Added in version 3.25.

Finds the DirectX Shader Compiler (DXC), including the library and command-line tool. Note that Visual Studio also provides a DXC tool, but the version included with the Vulkan SDK is typically required for Vulkan development, as it has Vulkan capability enabled.

volk

Added in version 3.25.

Finds the Vulkan meta-loader volk library, a vector-optimized library of kernels.

Imported Targets

This module provides the following Imported Targets:

Vulkan::Vulkan

Target encapsulating the main Vulkan library usage requirements, available if Vulkan is found.

Vulkan::glslc

Added in version 3.19.

Imported executable target encapsulating the GLSLC SPIR-V compiler usage requirements, available if glslc is found.

Vulkan::Headers

Added in version 3.21.

Target encapsulating the usage requirements needed to include Vulkan headers. It provides only the include directories and does not link to any library. This is useful for applications that load the Vulkan library dynamically at runtime. This target is available if Vulkan is found.

Vulkan::glslangValidator

Added in version 3.21.

Imported executable target encapsulating the glslangValidator usage requirements, available if this tool is found.

Vulkan::glslang

Added in version 3.24.

Target encapsulating the glslang library usage requirements, available if glslang is found in the SDK.

Vulkan::shaderc_combined

Added in version 3.24.

Target encapsulating the shaderc_combined library usage requirements, available if this library is found in the SDK.

Vulkan::SPIRV-Tools

Added in version 3.24.

Target encapsulating the SPIRV-Tools library usage requirements, available if this library is found in the SDK.

Vulkan::MoltenVK

Added in version 3.24.

Target encapsulating the MoltenVK library usage requirements, available if this library is found in the SDK.

Vulkan::volk

Added in version 3.25.

Target encapsulating the volk library usage requirements, available if volk is found in the SDK.

Vulkan::dxc_lib

Added in version 3.25.

Target encapsulating the usage requirements for the DirectX shader compiler library, available if DXC library is found in the SDK.

Vulkan::dxc_exe

Added in version 3.25.

Imported executable target providing usage requirements for the DirectX shader compiler CLI tool, available if SDK has this tool.
