link grpcclient_static error. undefined reference to grpc

[weizhenhuan]

I write a code with tritionserver cpp client, and then compile it using CMAKE:

add_executable(main main.cpp)
target_link_libraries(main PUBLIC grpcclient_static ${TORCH_LIBRARIES})

I find that in your example/simple_grpc_infer_client.cpp and it's CMAKE file，it only links grpcclient_static:

  #
  # simple_grpc_infer_client
  #
  add_executable(simple_grpc_infer_client simple_grpc_infer_client.cc)
  target_link_libraries(
    simple_grpc_infer_client
    PRIVATE
      grpcclient_static
  )

But when I compile my code, it gives the following error:
