[erlang-questions] erlzmq2 as rebar3 depency

[Dmitry Kolesnikov]

Hello,

Try to add to your rebar.config

```
{deps, [
   {erlzmq, {git, "https://github.com/zeromq/erlzmq2.git"}}
]}.

{plugins, [pc]}.

{overrides, [
   {override, erlzmq, [
      {plugins, [pc]},

      {provider_hooks, [
         {post, [
            {compile, {pc, compile}},
            {clean, {pc, clean}}
         ]}
      ]}
   ]}
]}.
```

It made a trick to me

```
1> erlzmq:context().
{ok,#Ref<0.2526647583.4010409989.113935>}
```
