# Shared libs default to OFF: we link static gRPC and the avx/avx2/avx512/fallback
# variants are fully static. The CPU_ALL_VARIANTS build flips SHARED_LIBS=ON (ggml/llama
# become shared so the dynamic CPU backends work; gRPC stays static via its imported
# targets). SHARED_LIBS is a make variable, not an appended -D, so it survives the
# recursive sub-make into the VARIANT build dir (which re-parses this Makefile) instead
# of being re-clobbered by a second -DBUILD_SHARED_LIBS=OFF. EXTRA_CMAKE_ARGS is the hook
# the CPU_ALL_VARIANTS target uses to inject -DGGML_BACKEND_DL/-DGGML_CPU_ALL_VARIANTS.

# Single-build CPU backend using ggml's CPU_ALL_VARIANTS. Produces ONE grpc-server
# plus a set of dlopen-able libggml-cpu-*.so (sandybridge/haswell/skylakex/...) that
# ggml's backend registry selects from at runtime by probing host CPU features.
# Replaces the avx/avx2/avx512/fallback multi-binary build on x86.
#
# CPU_ALL_VARIANTS requires GGML_BACKEND_DL, which requires BUILD_SHARED_LIBS=ON, so we
# pass SHARED_LIBS=ON and the DL flags as make variables (NOT pre-expanded into the
# CMAKE_ARGS env string): command-line make variables propagate through every recursive
# sub-make, so the deepest VARIANT-dir build computes BUILD_SHARED_LIBS=ON consistently.
# Only ggml/llama go shared - gRPC is found via its static imported targets, so the
# grpc-server binary keeps static gRPC and only dynamically links ggml.
#
# TARGET adds "ggml": the per-microarch backends are runtime-dlopened, not link deps of
# grpc-server, so they only build because each is an add_dependencies() of the ggml target.
