Heltec_CubeCell_AB02A and multi sensor example not compiling

Hi I’m trying to compile (Arduino 1.8.19) the LoRaWAN_Multi sensor example. The compiler fails with
a lot of errors, this is just a top of the output but it will give an idea. There is obviously something fundamental I’m missing.
CubeCell_AB02A 1/2 AA is the board.

Any help would be appreciated

I had the additional files in the directory with the .ino file and edited the file removing the include/ to reflect this change.
Then I run into a problem which was caused by the entry GPIO0 which I replaced with GPIO1 and now it compiles fine.

Maybe this will help someone else
