How do I configure lsp-mode to actually find the AVR headers? As an
example I'm getting errors (file not found) for avr/io.h and other AVR
specific headers.

EDIT: I use clangd.

I'm going to assume you're using `clangd`. The proper way is to
generate a `compile_commands.json`:

https://clang.llvm.org/docs/JSONCompilationDatabase.html

You can also just throw this in a file, `.clangd`, at your project's
root:

    CompileFlags:
      Add:
        - "-I/usr/include/<nested_include>"
        - "-I/home/you/code/c/projects/<project>/include"

Thanks, you assumed correctly, sorry for not including this info.

There's a number of projects to autogenerate `compile_commands.json`.
For make based projects I use
