Recent Arduino IDE releases include the Library Manager for easy installation. Otherwise, to download, click the DOWNLOAD ZIP button, uncompress and rename the uncompressed folder Adafruit_GFX. Confirm that the Adafruit_GFX folder contains Adafruit_GFX.cpp and Adafruit_GFX.h. Place the Adafruit_GFX library folder your ArduinoSketchFolder/Libraries/ folder. You may need to create the Libraries subfolder if its your first library. Restart the IDE.
**You will also need to install the latest Adafruit BusIO library.** Search for "Adafruit BusIO" in the library manager, or install by hand from https://github.com/adafruit/Adafruit_BusIO
