Arduino IDE build for M5Stickc

[tcahall]

I am trying to compile the listener for an M5stick and getting a missing SensorDataStruc.h. Web searches haven't located the missing file. Error below.

Are all libraries listed in https://github.com/josephdadams/TallyArbiter/blob/master/listener_clients/m5stickc-listener/README.md included?
Which version of Arduino IDE are you using? I compiled it successfully on v2.3.2 on Windows 10.
