added the Waveshare 128x64, 1.3inch OLED display HAT to the MT32-Pi lite

I added the Waveshare 128x64, 1.3inch OLED display HAT to the MT32-Pi lite and was able to get the OLED display to work fine. I needed to change some changes to make the display support I2C. Then I went for the buttons and the joystick to make them work. The pins are differently assigned that the ones of the original design. So, I decided to compile the project from source and I faced some issues. To start with, just cloning the project from github and trying to make it does not work. Then I found that I used to use --recursive to pull some dependencies. After I got the kernel8 file compiled, I was able to get the buttons and the joystick to work but no I do not have audio.
I was wondering, if it is possible to have a simple guide on how to compile the project from source.
If possible, someone make the kernel for me with the following changes:
Button 1 or Synth = P21
Button 2 or ROM = P16
Button 3 or Vol DN = P19
Button 4 or VolUP = P6

This is for the Raspberry Pi Zero 2 used in the MT32-Pi Lite.

Thank you in advance

OK, so it turned out the compile did not have any issue. However, assigning P21, P16, P19 and P6 as buttons will interfere with the audio (Pi to MisTer) interface.
