Adafruit_ILI9486_STM32 - does not compile with my STM32 package

The graphicstest demo example does not compile for STM-Nucleo F103RB of my STM32 Arduino package.

The library used is from

The STM32 package has been loaded by adding

This library would help me getting started with my Raspberry Pi display on Arduino

looks like an inofficial SPI library is needed:

#include <SPI.h> // Using library SPI in folder: D:\Documents\Arduino\hardware\Arduino_STM32\STM32F1\libraries\SPI
