# turboquant is a llama.cpp fork. Rather than duplicating grpc-server.cpp / CMakeLists.txt /
# prepare.sh we reuse the ones in backend/cpp/llama-cpp, and only swap which repo+sha the
# fetch step pulls. Each flavor target copies ../llama-cpp into a sibling ../turboquant-<flavor>-build
# directory, then invokes llama-cpp's own build-llama-cpp-grpc-server with LLAMA_REPO/LLAMA_VERSION
# overridden to point at the fork.

# Each flavor target:
#   1. copies backend/cpp/llama-cpp/ (grpc-server.cpp + prepare.sh + CMakeLists.txt + Makefile)
#      into a sibling turboquant-<flavor>-build directory;
#   2. clones the turboquant fork into turboquant-<flavor>-build/llama.cpp via the copy's
#      own `llama.cpp` target, overriding LLAMA_REPO/LLAMA_VERSION;
#   3. applies patches from backend/cpp/turboquant/patches/ to the cloned fork sources
#      (needed until the fork catches up with upstream server-context.cpp changes);
#   4. runs the copy's `grpc-server` target, which produces the binary we copy up as
#      turboquant-<flavor>.
