Newbie: need some hand holding. about arduino-cmake-ng HOT 2 CLOSED

@rileyrg Hi and welcome to the Arduino-CMake project!
I'm sorry to hear that you're having such a hard time using this framework.

Reviewing your logs, I suspect you've cloned the master branch of this repo, which is not the stable branch as it is in some other git repos! Instead, here it acts as the main dev branch, while official releases are bundled with GitHub's Releases. Use them (Desirably the latest one).

As for the board_id dimness - The function is nowhere to be found on Google since it's defined by the framework and not documented anywhere in the Wiki (Not as a standalone function at least).
Generally what it does is constructing a string combining both the ID of the board to be used and possibly its' CPU, that later should be passed as an argument to many other API functions.
Just to make it clear, take for example the Uno board you've mentioned - It's not only the name of the board's model, but also it's ID (According to Arduino, not this framework). This is usually like this.
However, looking at the example we see the nano board ID and a possibly strange string, atmega328. This is the board's CPU, and it's required because some boards are compatible with multiple CPUs.
You shouldn't worry about that, just get some basic info about your board in advance.
Back to the get_board_id function - This entire concept you see in the example is about to be deprecated (In fact it's already deprecated in master, however not documented yet), omitting the use the board_id argument by users like you entirely.
With that being said - Please follow the Wiki docs (And the above explanation) until the new version is officially released.

Now one last thing regarding boards - You've mentioned the Elegoo Uno R3 board, however, I'm not sure it's entirely supported by the framework yet. It seems to be a 3rd party platform, i.e. not plain, native Arduino, which is currently not supported.
You should first try to use the project after reading what I've written above, but if that doesn't work - Do not be so surprised 😞

I hope I was able to en-light your path to happy Arduino-CMake development! 😄
