+## Apple RDMA link fixup.

+## ggml-rpc hands Apple's librdma to the linker with
+## target_link_options(ggml-rpc PRIVATE "LINKER:-weak_library,..."). Link options are not
+## a usage requirement of a static library, so in our BUILD_SHARED_LIBS=OFF build the flag
+## dies with libggml-rpc.a and every ibv_* symbol transport-apple.cpp reaches for comes out
+## undefined when grpc-server and ggml-rpc-server link. Re-declare the same weak link as
+## INTERFACE so it travels to whoever links the static library.
+##
+## Guarded on the marker so a second prepare.sh over the same checkout is a no-op, and on
+## GGML_RPC_RDMA_APPLE so forks that branched before the Apple RDMA transport (turboquant,
+## bonsai) are left alone.
