I’m trying to setup a `CMakePresets.json` file, included below. When I try to use it, I get a very basic error message: “Invalid preset”, with no details or context. I’ve validated this against the published schema, but there are no errors reported. I’ve double checked it against the documentation, but I don’t see any issues.
Is this a bug in the parser, or a problem with my file?

Ah, solved it – I had a typo in one of the inherit fields, `s/system_/systems_/` seems to fix it.
Sorry for the noise, and looking forward to [https://gitlab.kitware.com/cmake/cmake/-/issues/21310](https://gitlab.kitware.com/cmake/cmake/-/issues/21310) 🙂

Is there a way to get the parser to help?
The error messages are not wrong but they are terse.
In your case it says “invalid preset” it would be more helpful if it said “base\_mc-system\_cuda is an invalid preset”.
I am currently getting “Duplicate presets” but I have many presets.
