Docs: Where to obtain prebuilt skia-win and coreclr-win-x64 bundles for External/?

[postleitzahl1234]

Summary

The README's Quick Start tells Windows users to "manually extract Skia and CoreCLR" into:

Luma/
├── External/
│ ├── coreclr-win-x64/
│ └── skia-win/

…but doesn't link to a download for these prebuilt bundles, and I couldn't find them anywhere public:

• This repo has no GitHub Releases
• No companion repo for binaries that I could locate
• The wiki has no setup page covering these
• No CSDN / Bilibili / Zhihu / Discord posts with download URLs
• The Discord invite in the README (discord.gg/BJBXcRkh) appears to be expired

External/CMakeLists.txt calls find_package(Skia REQUIRED) and find_package(DotNetRuntime REQUIRED), with Skia_DIR and DotNetRuntime_DIR pointed at those exact folders — so each bundle must ship its own SkiaConfig.cmake / DotNetRuntimeConfig.cmake plus headers and libs. Generic upstream Skia / .NET runtime downloads don't satisfy that layout.

What I'm asking for

Could you publish (or link to) the two prebuilt bundles that match what External/CMakeLists.txt expects? Ideally as a GitHub Release attached to this repo, but a Gitee / Baidu Pan / OneDrive mirror is fine too.

Specifically I'd need:

1. skia-win/ — Skia bundle with a config file exposing Skia::Skia (the CMake target referenced in External/CMakeLists.txt), plus headers and lib(s).
2. coreclr-win-x64/ — CoreCLR bundle with a config file exposing DotNet::Host, plus the runtime DLLs (coreclr.dll, hostpolicy.dll, hostfxr.dll, nethost.dll), nethost.lib, and nethost.h / hostfxr.h / coreclr_delegates.h.

If publishing them isn't feasible right now, even a brief note describing the expected directory layout and the Skia commit / build flags you used would let me assemble compatible bundles locally.

What I've already done

• Installed Git, CMake 4.3, Vulkan SDK 1.4.350, VS 2022 Community with the "Desktop development with C++" workload, .NET 9 SDK
• Bootstrapped vcpkg and ran vcpkg install openssl curl ffmpeg
• Successfully assembled External/coreclr-win-x64/ by hand from the locally-installed .NET 9 SDK (runtime DLLs from dotnet/shared/Microsoft.NETCore.App/9.0.12, nethost.lib + headers from dotnet/packs/Microsoft.NETCore.App.Host.win-x64/9.0.12/runtimes/win-x64/native) plus a hand-written DotNetRuntimeConfig.cmake exposing DotNet::Host — looks plausible, untested at link time.
• Skia is the remaining blocker — too many ABI-breaking commits to confidently guess which build to use.

Environment

• Windows 11 Pro 26200
• Visual Studio Community 2022 17.14 (Desktop development with C++)
• CMake 4.3.2 / Vulkan SDK 1.4.350.0
• vcpkg latest (2026-04-08)
• .NET 9 SDK 9.0.310

Thanks for the engine — happy to help update the README with build steps once I have a working setup.
