QVAC vcpkg Registry

A vcpkg custom registry used by QVAC projects. It provides versioned ports for inference, TTS, and supporting libraries, including some packages not available (or not at the versions we need) in the official vcpkg registry.

What’s in this registry

• QVAC packages: qvac-lib-inference-addon-cpp, qvac-lint-cpp
• Inference / ML: llama-cpp, speech-cpp, stable-diffusion-cpp, onnxruntime, onnx, tokenizers-cpp, sentencepiece
• ggml flavours: ggml, ggml-speech
• Build / runtime deps: vcpkg-cmake, vcpkg-cmake-config, vcpkg-cmake-get-vars, abseil, eigen3, opencl, opencl-headers, protobuf, pybind11, xnnpack, and others

Exact versions and baselines are defined in versions/baseline.json.

The speech stack: speech-cpp

speech-cpp is an umbrella port over qvac-ext-lib-whisper.cpp: one source pin for the whole speech stack, with the engines selected as features and every engine linking the single ggml-speech ggml.

Feature	Engine	find_package	Imported target
whisper	whisper.cpp transcription	whisper	whisper::whisper
parakeet	Parakeet ASR + diarization	qvac-parakeet	qvac::parakeet
tts	Chatterbox, Supertonic, CosyVoice3, Parler, Audio8, LavaSR	tts-cpp	tts-cpp::tts-cpp
audiogen	ACE-Step music generation	audiogen-cpp	audiogen-cpp::audiogen-cpp

Backend features (metal, vulkan, opencl) fan out to the matching ggml-speech features, so a manifest entry like the one below resolves one shared ggml-speech with unified features:

{
  "name": "speech-cpp",
  "default-features": false,
  "features": ["whisper", "parakeet", "vulkan"]
}

speech-cpp replaced the per-engine whisper-cpp, parakeet-cpp, tts-cpp and audiogen-cpp ports, which pinned the same upstream repo at four different commits. Those ports were removed once every consumer had migrated, so manifests that still name them no longer resolve — depend on the matching speech-cpp feature instead.

Prerequisites

• vcpkg (manifest mode or classic)
• For manifest mode: a vcpkg.json in your project
• For classic mode: a vcpkg installation and use of vcpkg install from a vcpkg root

Setup: use this registry in your project

1. Use the canonical registry URL
   https://github.com/tetherto/qvac-registry-vcpkg.git

2. Configure the registry in your project so vcpkg can find it.

   Manifest mode
   Add a vcpkg-configuration.json next to your project’s vcpkg.json (or in your vcpkg root), for example:

   {
     "registries": [
       {
         "kind": "git",
         "repository": "https://github.com/tetherto/qvac-registry-vcpkg.git",
         "baseline": "main",
         "packages": [
           "qvac-lib-inference-addon-cpp",
           "qvac-lint-cpp",
           "llama-cpp",
           "speech-cpp",
           "ggml-speech",
           "onnxruntime"
         ]
       }
     ]
   }

   To allow all packages from this registry (and still use the official registry for everything else), set:

   "packages": ["*"]

   Classic mode
   Create or edit vcpkg-configuration.json in your vcpkg installation root (e.g. vcpkg_installed or your clone of vcpkg) with the same registries block as above.

3. Declare dependencies in your project’s vcpkg.json (manifest mode) or install them via the CLI (classic mode), e.g.:

   "dependencies": [
     "qvac-lib-inference-addon-cpp",
     "llama-cpp"
   ]

   Then run your usual vcpkg install/build (e.g. CMake with vcpkg toolchain, or vcpkg install).

Summary

Step	Action
1	Ensure vcpkg is installed and your project uses it (manifest or classic).
2	Add this registry in vcpkg-configuration.json with kind: "git", repository: https://github.com/tetherto/qvac-registry-vcpkg.git, and a baseline (e.g. main or a commit/tag).
3	List needed packages in "packages" or use ["*"] to allow all.
4	Add the ports you need in your vcpkg.json or install them via the vcpkg CLI.
