Typhoeous Won't Build on Windows

I’ve been going through the build instructions located here:

https://github.com/diaspora/diaspora/wiki/Installing-on-Windows-XP

I’ve gotten up to the Typhoeous section. Originally, Typhoeous would not compile cause it could not find the source code for libcurl. After figuring out that I had to download libcurl to a separate location, and then reference that location (as outlined here: https://github.com/dbalatero/typhoeus/issues/11) I am now getting a different error.

I believe the pertinent part of the error message is this:

checking for curl_easy_init() in -lcurl... no

You can see the full error output here:
