Probably just need to update GRPC grpc/grpc#10589

There is a work-in-progress to resolve this over at #1853.
Feel free to help out!

I tried to compile 1.14.36.1, I get the following errors:

looks like ssl issue as well

I was googling this issue and stumbled upon this discussion https://www.mail-archive.com/users@subversion.apache.org/msg27957.html. It seems the problem is that the latest serf release was in 2016 so it doesn't fully support openssl 1.1. A guy from apache recommends to use version 1.4, it says it quite stable
