Just some notes for the next person that has this issue, because it wasn't 
immediately obvious what to do...

The above issue was on Windows. When building Qt on OSX, QtWebkit gets built 
with OpenSSL support by default, at least that's what happened when I built it, 
which is why I was confused about it not being available on Windows.

To get WebKit built on Windows you need to install and build icu 
(http://site.icu-project.org/), add -icu to the configure command and set the 
INCLUDE and LIB env vars, and install the extra tools as described here:
http://doc.qt.digia.com/qt-5.2/windows-requirements.html
Also the icu bin dir has to be on your path.

That should get QtWebKit built, but it won't have SSL support. For that you need 
to build OpenSSL from openssl.org, add it to the INCLUDE and LIB env vars and 
add -openssl to the configure line.
