faild to link protobuf

Question

I'm trying to link protobuf but I'm getting an undefined reference: this is my CMAKE file: I also see in the error code it has a problem with the std::string of the ABI of CPP11 but I don't know if this is the main problem or not because I'm building from a source using GCC 7.3.1

cmake_minimum_required(VERSION 3.17)
project(cpp_server_side_objects)

set(CMAKE_CXX_STANDARD 17)

SET(BOOST_LIB boost_system boost_thread)

INCLUDE(FindProtobuf)
FIND_PACKAGE(Protobuf  REQUIRED)
if(Protobuf_VERBOSE)
    message(STATUS "Using Protocol Buffers ${Protobuf_VERSION}")
    else()
    message(STATUS "cant find protobuf ${Protobuf_VERSION}")
endif()
INCLUDE_DIRECTORIES(${PROTOBUF_INCLUDE_DIR})
PROTOBUF_GENERATE_CPP(PROTO_SRC PROTO_HEADER SREXOrderRequest.proto)
ADD_LIBRARY(proto ${PROTO_HEADER} ${PROTO_SRC})


add_executable(cpp_server_side_objects main.cpp request.cpp request.h)
target_link_libraries(cpp_server_side_objects proto ${PROTOBUF_LIBRARY} ${BOOST_LIB} )

but I'm getting this error messages:

how to fix it? tried using this and this and this and with thisalso with no luck.

If you have checked [that question](https://stackoverflow.com/questions/41043184/cmake-doesnt-work-with-google-protobuf), then why do you use **wrong variable name** - `PROTOBUF_LIBRARY` - instead of the correct one - `Protobuf_LIBRARIES`? — Tsyvarev, Feb 11 '21 at 12:29
@Tsyvarev I change the `target_link_libraries` line from `${PROTOBUF_LIBRARY}` to `${Protobuf_LIBRARIES}` and still the same errors — yaodav, Feb 11 '21 at 12:37
Try `find_package(Protobuf CONFIG REQUIRED)` followed by `target_link_libraries(... protobuf::libprotobuf)` — rustyx, Feb 13 '21 at 12:19
