What are ZMQ_BUILD_DRAFT_API, ZMQ_CPP11 and ZMQ_HAVE_POLLER? #175
Description
I've didn't pay attention to these macros and after some hours compiling everything in my docker file I realized I'll have to activate them to have poller_t. Why would someone not want to have poller, and what are ZMQ_BUILD_DRAFT_API and ZMQ_CPP11? Does ZMQ_BUILD_DRAFT_API mean you guys didn't come up with a full API for things like poller_t? ZMQ_CPP11 means I can choose to use cpp11 or before?
(also, how to enable them at compile time? I'm not familiar with cmake)
