64-bit machines and standard udt location

Silly Stephen, always compiling on 32bit.

And maybe I'm a wizard, because I got this to build. Or maybe an apprentice wizard, since I've only done turbolib so far.

To build:
clone repo (fork first if you're like me)
apt-get install libtbb-dev
apt-get install libudt-dev
cmake .
cmake --build .
ctest
???
profit!

Also, you have a race in the event unit test, it failed on me once. That's all the info I have sadly.

This was to get things building on my box to address a bug I saw, but I'll have to fix that another day.
