Were you able to resolve the problem or are you still stumped?
It builds for me on an Ubuntu Intel box so not sure why it's failing for you..
Possibly you're running it on an Intel PC that doesn't have SSSE3 instructions?
I used another machine where it works fine. It still fails on my first machine.

AMD without SSSE3
Ah okay. I think the issue is that the build flags need to be set to include SSSE3 with -m argument, and we should do runtime detection of the feature. But I'm lazy!
The code already does runtime detection of feature would just need to update the CMakeLists.txt somehow
I suggest to add travis.ci or any other CI system to check builds.
