Is there a way to disable certain components of the IDF?

I understand that unused components are not included in the image (app), but my problem is that every time I need to a compilation (of even one single file), idf is checking ALL components for changes and it really takes a while, it's frustrating. There are quite a few components I will never use, so I'd like to at least disable them.

Hi, In your project level CMakeLists.txt file, you may set COMPONENTS like before the call to to restrict the number of components that are built.

Yeah, works, thanks!

A few notes:
- many components remain active nonetheless because other components depend on them (which was to be expected)
- a few components (in my case: bt, esp_psram, wear_levelling) must be included explicitly otherwise the functionality will lack
- most components (all minus above and minus "main") can be left out anyway
- this will mess with your sdkconfig file. Make sure you make a backup first or be prepared to all configuring from scratch
- compare original and adjusted sdkconfig to see what components are missing (their config will be removed), if some are actually required, you can add them manually
- look in esp-idf/components for components' names. Don't be fooled by the output of idf (using __some_name) that's not what this option expects.
