MQTT Client in C++

Hi, I have a current project and would like to add MQTT messaging. Please create a class / library that I can easily add to my project so I can subscribe to 4 topics to a broker on localhost, and publish to 2 topics on the broker. I only need simple messaging with QOS 0, and also send username and password to broker on connect. Continue retry connection if first connection did not work, Reconnect if connection lost. Subscription will return a text string as payload when a message arrives, and publish only need to send text string as payload as well. OS is Ubuntu v18 on Arm64 Please ask if you need more information. Thank you, Chris
