Description

On macOS and Ubuntu 17, libevent-openssl >= 2.1.x is broken in conjunction with libprocess.

We tried to pinpoint the issue but so far with no success. For enabling CMake SSL builds on those systems , we have to support prior libevent versions. Allowing building against a preinstalled libevent version paves that way.
