AFAIK hyperscan has no plans for platforms other than amd64 ((

There is a https://github.com/VectorCamp/vectorscan project. They should be almost API compatible with hyperscan and support more architectures. Adding an option to build with them could be nice.

I've added a cmake option to build klogg with vectorscan, passing -DKLOGG_USE_HYPERSCAN=OFF -DKLOGG_USE_VECTORSCAN=ON should make klogg use vectorscan backend.
