IDE version: 1.8.13 (Windows Store 1.8.42.0)

Action: Compiling example sketch for Heltec ESP32 Wifi board.

I've found an issue with include files when the path+file is particularly long under the ArduinoData/packages folder (> 210).

Compiler bails with error "file not found" for some header files. The real reason is the length of the path.
I've modified some of the header files to have shorter names, bringing the size of path+file under 210 chars.
By renaming and shortening the paths, I was able to compile and run the project without issue.

For info, my "user name" under c:\users is 44 char longs. Needless to say I can't change this.
Any workaround, like moving the ArduinoData folder to an arbitrary location?
