One of the Hyperscan developers commented on HN slightly over a year ago [1] that Intel had basically abandoned Hyperscan due to lack of sufficiently vocal customer interest. I hope that has changed, or is in the process of changing, because Hyperscan remains amazing.
The official repo[1] is looking pretty dead.
Edit: This is a surprisingly heavy build. Over 15 minutes on my somewhat older i5. I suggest using make -j instead of cmake -build to speed it up. Decent number of compiler warnings too.
