Project has Configurable Options

Running AWS>IoT>Controlled_Publish_Period script provided with Zerynth. Followed the process to complete congif file, load cert/key and add wifi ssid/psswd. Keep getting these warnings during compilation:
[warning] This project has configurable options!
[warning] Options for module espressif.esp32net.esp32wifi ::
[warning] ZERYNTH_SSL enabled

I don’t see any other configurable parameters in the code. Is this important?
