Hey, thanks for reporting. Currently, the network protocol is not supported on Windows, as it assumes a Berkeley sockets style API.
I'm guarding the network code with a simple #ifndef WINDOWS. Reworking these guards is needed to get it building on MINGW environments.
I don't have a MINGW environment available, but the included instructions in the README on how to build natively on Windows should still work.

Shouldn't it be #ifndef _WIN32? Your usage of #ifndef WINDOWS is wrong. This is the reason why <arpa/inet.h> is still included.

Oh I see, -DWINDOWS is added by you on your CMakeLists.txt. @vkoskiv What about replacing #ifndef WINDOWS in code with #ifndef _WIN32 so you will not need to define -DWINDOWS on CMakeLists.txt? Btw, please have a look at your CMakeLists.txt and add support for MinGW compiler. You could use if (MinGW) to check for MinGW on CMake. Currently you only check for MSVC so -DWINDOWS is not defined when building with MSYS2.

I personally don't have a need for MinGW support, nor a test environment to implement that support, but I'd be happy to merge in those changes if someone else works on it.
