Arduino IDE can't look inside subfolders subdirectories except src

[galtthedestroyer]

I thought Duinocoin was supposed to be easy to get into. I've never used Arduino before. I open Arduino_Code.ino in the Arduino IDE version 2.1.0.5. That's the only version available in my distro's repos. I click verify. The error is:

sha1/default.h no such file or directory

After some digging around on the interwebs I found that after IDE version 1.6 or so it's behavior is restricted to looking only inside a src folder. So I moved everyting into a src folder that I created. Then the IDE complained that my ino file must exist inside a directory with the same name. I thought to just copy paste everything in the sha1 folder into the main folder and adjust the INCLUDE statements. But there's already a file there called sha1.h. I tried "add library" both with the sha1 folder and the entire original zip file.

This is ridiculous! How has no one else had this problem!

I found this after searching "directory" #840

It doesn't help. My IDE doesn't have that menu option. earlier I searched for subfolder and subdirectory and src. None of those found anything.

I grabbed the current IDE from flatpak and that works just fine.
