Qt MQTT is part of the Qt for Automation offering and not Qt

https://doc.qt.io/QtForAutomation/qt...-install.html#
Install from the pre-built binaries available through your commercial account, or build from source.

I am also facing similar issues. How to connect to your MQTT broker on QT creator Open source version 5.1.14 ? How to install the required libraries. I am a newbie into QT and I would appreciate answers that are as detailed as possible.

ChrisW67 already gave you the answer to this question. If you have a Qt Commercial account, then you can download pre-built binaries as part of your account service. If you are using open source, then you have to download the source code and compile it yourself. The link he posted takes you directly to the appropriate instructions.
