Cannot make successfully with -DLOGGING_ENABLED=1 : "error: expected unqualified-id"

cpp-redis version : master 99b1dda

Describe the bug
I'm following the build instructions here: https://github.com/cpp-redis/cpp_redis/wiki/Mac-&-Linux-Install
With the logging enabled flag as described here: https://github.com/cpp-redis/cpp_redis/wiki/Compilation-and-installation-options#enable-logging

The make step fails with:

Looks like the solution is to replace the int value with warn/debug/etc as done in this PR (https://github.com/cpp-redis/cpp_redis/pull/69/files).
