Adds vcpkg as a submodule at vcpkg/, pinned to the exact commit vcpkg.json already declares as builtin-baseline, so the bundled checkout and the manifest's resolved port versions can never drift apart. cmake/voicecat-toolchain.cmake, scripts/common.sh, and clients/apple/scripts/build-xcframework.sh now resolve vcpkg as: VCPKG_ROOT env var (external checkout) > bundled submodule. Docs updated to describe the new one-time setup. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

# cmake/voicecat-toolchain.cmake — vcpkg toolchain wrapper with auto-triplet.
|
|
#
|
|
# Wraps vcpkg's toolchain to auto-resolve VCPKG_HOST_TRIPLET and VCPKG_TARGET_TRIPLET
|
|
# from the host platform, so the main presets (dev, release, server-release) build on
|
|
# Windows/MinGW, Linux, and macOS without per-OS preset variants.
|
|
#
|
|
# Triplet mapping (auto):
|
|
# Windows → x64-mingw-static (the project's toolchain is MSYS2/UCRT64 — see
|
|
# clients/windows/README.md; MSVC users must set
|
|
# VCPKG_TARGET_TRIPLET=x64-windows explicitly)
|
|
# Linux x64 → x64-linux
|
|
# Linux arm64 → arm64-linux
|
|
# macOS arm64 → arm64-osx (Apple Silicon)
|
|
# macOS x64 → x64-osx (Intel)
|
|
#
|
|
# Cross-compile presets (apple-ios, apple-ios-sim) set VCPKG_TARGET_TRIPLET explicitly
|
|
# in their cacheVariables; the DEFINED guards below preserve those. VCPKG_HOST_TRIPLET
|
|
# is always the host's (e.g. arm64-osx when cross-compiling iOS on Apple Silicon).
|
|
#
|
|
# Resolution order: an explicit VCPKG_ROOT env var always wins (for developers pointing at
|
|
# their own external vcpkg checkout); otherwise this falls back to the bundled submodule at
|
|
# <repo-root>/vcpkg (`git submodule update --init vcpkg`).
