MQTT with Legato 16.10.1 SW FX30S

I was trying to use that code GitHub - startwithsierra/utils-legato-mqtt: Legato MQTT client, but i cant use it from Developer Studio because some libraries cant be linked. The error is:
“C:\Legato\workspace\pruebaLegatoMqtt/pruebaLegatoMqttComponent/src/json/swir_json.c:17:32: fatal error: src/json/swir_json.h: No such file or directory”

The code that you send is like compile a full firmware an install it on the equipment, is that right?
