Compiler failing to find header files for SSD1306

Libraries

I’m trying to hook an SSD1306 to my XIAO and the compiler is failing to find the header files for the library. Any suggestions?

So, did you add that dependency too? It can find the header file for the SSD1306, just not the GFX dependency.

lib_deps = 
  adafruit/Adafruit SSD1306 @ ^2.4.2
  adafruit/Adafruit GFX Library @ ^1.10.4
  adafruit/Adafruit BusIO @ ^1.7.1

Thanks! It turned out to be not referencing the correct libraries in the script.
