Alien-Librdkafka dependency needs bumping to 0.11.6 or later for header support #52
Description
As mentioned in this comment, PR #48 introduced header support but didn't bump Alien-Librdkafka to a version with header support, i.e. v0.11.6 or later. Building this distribution against the older Alien-Librdkafka-0.9.3 causes compiler errors:
