Couldn't initialize SDL (No available video device) while running AlephOne

Hello,
I’m trying to build and run AlephOne. I downloaded the source files from the website. Output from “uname”:

5.13.0-30-generic #33~20.04.1-Ubuntu SMP Mon Feb 7 14:25:10 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

I originally downloaded the SDL2 packages separately. I believe I compiled the wrong packages or compiled them in the wrong order. I then I followed the instructions here:

These are the warnings and errors that I AlephOne on git:
They want to pass it of so I am contacting you.

I fixed the issue by first compiling SDL2-2.0.20 from source, then compiling AlephOne. So I must have compiled the wrong libraries or installed the wrong packages.
