CMake is an open-source, cross-platform tool designed to build, test
and package software. CMake controls the software compilation using
simple platform and compiler independent configuration files, and
generate native makefiles and workspaces that can be used in compiler
environments like Windows, Mac OS, BSD and Linux.

$ cd build
$ cmake -DPAHO_MQTT_C_PATH=/tmp/paho-c ..
On Windows, open the CMake GUI and "configure" the Visual Studio
build. On the GUI interface, set the PAHO_MQTT_C_PATH and "generate"
the build files.
