KWin does an unconditional find_package(Vulkan REQUIRED), and CMake's
FindVulkan needs BOTH Vulkan_INCLUDE_DIR and Vulkan_LIBRARY. Mesa already
builds the Vulkan drivers (libvulkan_intel/_radeon/_lvp) but an ICD is not
the API surface a consumer links against, so kwin could not configure.
vulkan-headers: header-only, but VulkanHeadersConfig.cmake is GENERATED at
install time rather than shipped in the tarball, and Vulkan-Loader
hard-requires it -- a hand copy of include/ satisfies FindVulkan and then
fails the loader. Run upstream's cmake install instead.
vulkan-loader: one real port. vk_loader_platform.h gates the whole POSIX
arm (DIRECTORY_SYMBOL, the dlopen wrappers, manifest search) on an OS list
that predates Redox, so the build collapsed with 'DIRECTORY_SYMBOL'
undeclared. Redox provides dlopen/dlsym and POSIX paths via relibc, so it
belongs in the same arm as Linux; that header is the only file under
loader/ doing OS detection. WSI backends are left off: Red Bear is
Wayland-only and the compositor talks to Mesa's ICDs directly.
Both shadow the untested recipes/wip/libs/graphics/{vulkan-headers,
libvulkan} via the local-over-WIP mechanism, per the WIP ownership rule
that the shipping version lives in local/recipes/.
Verified: kwin now reports
-- Found Vulkan: .../sysroot/lib/libvulkan.so (found version 1.4.321)
kwin also gains its missing kf6-knewstuff dep -- its
find_package(KF6 COMPONENTS NewStuff) is REQUIRED, so without the dep the
framework was never staged into kwin's sysroot.
Vulkan Loader
This project provides the Khronos official Vulkan Loader for all platforms except Android
Introduction
Vulkan is an explicit API, enabling direct control over how GPUs actually work. As such, Vulkan supports systems that have multiple GPUs, each running with a different driver, or ICD (Installable Client Driver). Vulkan also supports multiple global contexts (instances, in Vulkan terminology). The ICD loader is a library that is placed between a Vulkan application and any number of Vulkan drivers, in order to support multiple drivers and the instance-level functionality that works across these drivers. Additionally, the loader manages inserting Vulkan layer libraries, such as validation layers, between an application and the drivers.
This repository contains the Vulkan loader that is used for Linux, Windows, MacOS, and iOS. There is also a separate loader, maintained by Google, which is used on Android.
The following components are available in this repository:

How to Build and Run
BUILD.md includes directions for building all components.
Architecture and interface information for the loader is in docs/LoaderInterfaceArchitecture.md.
Version Tagging Scheme
Updates to this repository which correspond to a new Vulkan specification release are tagged using the following format: v<version> (e.g., v1.3.266).
Note: Marked version releases have undergone thorough testing but do not imply the same quality level as SDK tags. SDK tags follow the vulkan-sdk-<version>.<patch> format (e.g., vulkan-sdk-1.3.266.0).
This scheme was adopted following the 1.3.266 Vulkan specification release.
