      Before you go any further, why are trying to Windows SDK/winsock when the whole point is to use Qt (which has support for sockets) for this sort of thing?

      Anyway, if you have to for some interoperation with another package, check your linker line. That is where it fails to find __imp_WSAStartup. IIRC you need something like -lws32_lib. But how this would interact with Qt's own use of sockets under Windows I do not know.

        @JonB hey, thank you for your response i have recently started to learn qt so i don't yet know it as well as i know winsock, can you specify what kind of like i should add to cmake (that's what i got from your comment at least) and/or how i would go about substituting this in qt?

          I don't use Qt for Windows nor do I use cmake, so you will need someone else for that.

          However, the most pertinent question, especially if you are a newcomer to Qt, is why are you wanting using the Windows SDK and winsock? Qt is platform-independent, so in general you don't need or want to use Windows-specific calls in your code, certainly when Qt provides QTcpSocket etc.?

            @wwwsharq you might consider to use a plain c++ or c project with Qt instead of trying projects with Qt Widgets

                      This is a cmake configuration error. Either you don't have WindowsSDK installed or it doesn't provide a cmake module for what you requested, or you have not pointed to cmake to find said module.

                        There is no need to search for this lib. Simply add it to target_link_libraries call

                            @Christian-Ehrlicher hello do you have a tutorial or site you would reccomend to learn what you just said that isn't the cmake website? i have not understood evrything there and saying add target_link_libraries call doesn't tell me much i have added that line plenty of times without any luck, just more errors

                            target_link_libraries(eccoci PRIVATE ws2_32)
                            

                            and the like i've tried already

                                  target_link_libraries(eccoci PRIVATE Qt${QT_VERSION_MAJOR}::Widgets)

                                  add_executable(Executive ${exec_src})

                                  You create a library but don't link it to your executable.
                                  Also you link the QtWidgets library private to your library which is wrong (as you expose QtWidgets stuff in your library to it's users). So either properly link public or link your executable also to QtWidgets.

                                    If you're using visual studio (and cl) by far the easiest way is to

                                    # pragma comment(lib, "ws2_32.lib")
                                    

                                    the less you need to mess with CMake or (build files in general) the better.

                                      Using some non-standard stuff instead standarized scripting is for sure much better.

                                        Nothing standard about "scripting" (which I believe you use to refer to CMake) . But yeah, some of us prefer to have things the easy way and some don't...
