If you look at [1] you will see that we do compile libh2o 2.2.6
ourselves during the build process for CentOS 7 and 8 because it's not
provided by the distribution, and install it. It is then statically
linked into dnsdist.
We are not very happy with that method and would prefer using a proper
libh2o-evloop package should one become available.

I hope that helps.
