Question: thoughts on adding a way to enable/disable all feature options?

[aychun]

While working on a project with 30+ feature options I found myself needing to repeatedly toggle all of the features to test both the minimal and full build configurations.

My questions are:

• Is there any plan or interest in adding a built-in option (ideally per-subproject) that can enable or disable all feature options at once? Something like -Ddisable_all_features=true (with a better variable name) that would proceed with the minimal build configuration.
• If not, do you think having this kind of feature could be useful and be aligned with Meson's development roadmap?

Thank you!

That is meson setup --auto-features=disabled, I think?

I was unaware of that setup flag, thank you for letting me know! Although I still wish if there was a command that disables all features at once, I think I could update the meson.option file to have all the features to be auto and use that flag for my use case.
