下面尝试三种生成方式(全部都在 WORKDIR=~/dev-workspace/wx/phxrpc 下执行)：

third_party/protobuf/bin/protoc -Ithird_party/protobuf/include -I./phxrpc/rpc --cpp_out=. ./phxrpc/rpc/phxrpc.proto

最后生成的结果在 $WORKDIR 里面，与cpp_out参数指定的目标一致，然后phxrpc.pb.h的namespace为protobuf_phxrpc_2eproto

third_party/protobuf/bin/protoc -Ithird_party/protobuf/include -I./phxrpc/rpc --cpp_out=./phxrpc/rpc ./phxrpc/rpc/phxrpc.proto

最后生成的结果在 $WORKDIR/phxrpc/rpc 里面，与cpp_out参数指定的目标一致，然后phxrpc.pb.h的namespace为protobuf_phxrpc_2eproto

third_party/protobuf/bin/protoc -Ithird_party/protobuf/include -I. --cpp_out=. ./phxrpc/rpc/phxrpc.proto

最后生成的结果在 $WORKDIR/phxrpc/rpc 里面，与cpp_out参数指定的目标不一致 ，然后 phxrpc.pb.h的namespace为 protobuf_phxrpc_2frpc_2fphxrpc_2eproto

第三种就是官方提供的生成pb.cc的方式，这种方式生成的代码，在另外一个proto文件引用才是正常的，可视为什么呢？
