Overview

A simple example to build an mqtt client based on an external mqtt paho c lib.

References

Lots of examples helped in making this:

• An external multilib downloader for cmake https://gist.github.com/roxlu/0108d45308a0434e27d4320396399153#file-cmakelists-txt-L54
• https://github.com/charlesnicholson/cmake-external-project-test/blob/master/CMakeLists.txt
• https://github.com/mfreiholz/cmake-example-external-project/blob/master/CMakeLists.txt
• Paho MQTT C https://github.com/eclipse/paho.mqtt.c

Building

On Posix platforms:

mkdir build && cd build && cmake -DCMAKE_INSTALL_PREFIX=. .. && make

Windows would have some slightly different steps.

Known Issues

There is a lot of cruft. Many things need to get cleaned up. Making it work on windows should get done. Add static linking as an alternative.
