# Standalone, CI-friendly build for the FunASR llama.cpp runtime.
#
# Fetches a pinned llama.cpp (which provides ggml + llama) and builds the runtime
# binaries against it — no manual copying into a llama.cpp checkout, no hardcoded
# paths. Linux / macOS / Windows, x64 / arm64. Static libs -> self-contained binaries.
#
#   cmake -B build -DCMAKE_BUILD_TYPE=Release
#   cmake --build build -j               # binaries land in build/bin/

# Build against a local checkout instead of fetching:
