编译gRPC相关示例程序时，出现如下链接错误：
/home/suph/.local/lib/libgrpc.a(message_compress.cc.o): In function `zlib_compress(grpc_slice_buffer*, grpc_slice_buffer*, int)':
message_compress.cc:(.text+0x5c8): undefined reference to `deflateInit2_'
message_compress.cc:(.text+0x62b): undefined reference to `deflate'
message_compress.cc:(.text+0x6ed): undefined reference to `deflateEnd'
/home/suph/.local/lib/libgrpc.a(message_compress.cc.o): In function `zlib_decompress(grpc_slice_buffer*, grpc_slice_buffer*, int)':
message_compress.cc:(.text+0x7b4): undefined reference to `inflateInit2_'
message_compress.cc:(.text+0x813): undefined reference to `inflate'
message_compress.cc:(.text+0x8a7): undefined reference to `inflateEnd'
collect2: error: ld returned 1 exit status
经查询上述报错中，相关符号在zlib库中定义。
进入grpc/thirdparty/zlib目录，ls查看当前目录为空。
git pull单独下载zlib库源码程序
重新编译安装gRPC
问题：zlib源码下载成功后，是否可以单独编译安装zlib，而不是要重新编译整个gRPC
