Help need IridiumSBD dependancies!

Great work but help!

What is the exact includes that this needs to be built with?

I have downloaded: Arduino-master Arduino-5-master ArduinoCore-avr-master cygwin

I'm guessing Arduino-5-master\cores\esp8266 ?

All have many versions of of what looks like the required src. I've tried including various files it complains many are missing but the list is huge!

I'm using STM32CubeIDE_1.15.0 which is basically Eclipse but stripped down for the STM32 bug.

I've installed cygwin as well to try and run BasicSend.ino but it needs setup. Some of the files look like they are needed from: C:\cygwin64\lib\gcc\x86_64-pc-cygwin\11\include\c++ ?

Any help appreciated.
