I suggest you try building it with the supported method (the msvc build
system in src/tools/msvc), and then inspect the difference.

You can also look up those references in the Microsoft docs (for each API
function there is a listing at the bottom of the page telling you which
header and library is needed). From doing that, AFAICT, you are missing
ws2_32.lib and secur32.lib.
