XPT2046_Touchscreen

You probably meant to sent the project files here instead of in the other thread (https://community.platformio.org/t/using-an-raspberry-pico-as-picoprobe-debugger-for-another-rp2040-based-board/38568/15?u=maxgerhardt).

The problem is exactly I’ve said above:

You lib_deps all these different libraries

lib_deps =
  adafruit/Adafruit GFX Library@^1.11.11
  adafruit/Adafruit ILI9341@^1.6.1
  https://github.com/PaulStoffregen/XPT2046_Touchscreen.git
  adafruit/Adafruit BusIO@^1.16.2

but you only ever

#include "XPT2046_Touchscreen.h"

PlatformIO will not properly resolve library dependencies if you don’t include them into your project. Hence, the build for Adafruit ILI9341, Adafruit BusIO etc fails horribly.

But, the problem is a while different one. You just copy-pasted the contents of the XPT2046_Touchscreen.cpp and XPT2046_Touchscreen.h file from the XPT2046_Touchscreen library into your project. That makes no sense. You already include the library’s code in lib_deps = https://github.com/PaulStoffregen/XPT2046_Touchscreen.git. Copying the files of that library again in your project makes no sense.

I would advise to just delete src/XPT2046_Touchscreen.cpp and src/XPT2046_Touchscreen.h, create a new file src/main.cpp and use this content
