I'm attempting to compile a program with the CLI via docker, but I'm getting errors because it isn't populating the preprocessor definitions from boards.txt.
The specific error is a byproduct of that, but in case someone is searching for it later, the error: USB_VID was not declared in this scope from cores/arduino/USBCore.cpp
I see the following when running the exact same command in and out of docker, note all the definitions from boards.txt when outside of docker.
(Only the first command is shown and line breaks added for clarity)
In docker

I tried checking the source code to see if I'm missing an env variable or something of the like, but go is not my forte and it's tough to trace the chain of execution.
Anyone have any suggestions?
FWIW the Dockerfile is:
