Some logs

mosquitto\lib\net_mosq.h(22): fatal error C1083: Cannot open include file: 'sys/socket.h': No such file or directory

mosquitto/lib/net_mosq.h

Lines 21 to 25 in 5dceeb9

	#ifndef WIN32
	# include <sys/socket.h>
	# include <unistd.h>
	#else
	# include <winsock2.h>

WIN32 is not a predefined macros in the latest msvc, maybe need to use _WIN32 instead of WIN32 or add add_definitions("-DWIN32") in cmakelists.
