The system cannot find the file specified. Error Compiling for Arduino board.

Arduino IDE
3.5in. TFT LCD
I was coding my Arduino board for a 3.5in. TFT LCD screen. When I attempted to upload the program and error message appeared. It read:

"Arduino: 1.8.5 (Windows 10), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"
readlink C:\Users\kyng_\OneDrive\Documents\Arduino\libraries\Adafruit_GFX\glcdfont.c: The system cannot find the file specified.
Error compiling for board Arduino/Genuino Mega or Mega 2560."

I moved the file glcdfont.c to Adafruit GFX since that's where the Arduino was looking. Even after I did that, the error still appeared. I also tried to fix the error in compiling the Arduino, but nothing changed.
If you may please help me, that would be helpful.
Thank you.

Do a search on this forum for issues with OneDrive. I think somebody found a workaround.

There is an explanation and a couple workarounds here:
