The thing is that I think libmicrohttpd.lib was compiled using /MD, so it causes some conflicts if I change it to /MT for my project as I'm linking to it statically (I just downloaded the binary for the sake of compiling it for him, did not compile on my own).
It doesn't matter now, he can just download the runtime for the sake of testing this thing as it isn't fully done yet and the compilation process is a mess for Windows and I have no will to fix it up right now.
