Ubuntu 20.04 - undefined reference to `rd_kafka_incremental_assign' about modern-cpp-kafka

Is this an issue with linking to the librdkafka-dev library?
confluentinc/librdkafka#95

[kenneth-jia]

No, @adammpolak The link errors mean you're using an old librdkafka release which doesn't support "incremental assignment", -- i.e. older than https://github.com/edenhill/librdkafka/releases/tag/v1.6.0
Please manually install the latest librdkafka release! Here's an example for installation, https://github.com/morganstanley/modern-cpp-kafka/blob/main/.github/workflows/kafka_api_ci_tests.yml#L132

@kenneth-jia I will give this a shot thank you

Following that install path worked thank you @kenneth-jia

It is odd because following the confluent install path made it seem like I had 1.9:

~/dev/modern-cpp-kafka/build$ sudo apt-get install librdkafka-dev

librdkafka-dev is already the newest version (1.9.0-1.cflt~ubu20).

Not sure why that did not work ^
