LGTM.

How about we prioritize loading the environment variables? so if I rely on one env var defined locally, there's no need to check and load the IDF_PATH (which may not exist)

The original comment:

for non-keyword cap words, check if it is defined in the environment variables

no idea why I put it here... I can't think of a real risk about it.

[hfudev]

overall the sequence could be

• additional_attr
• IDF_TARGET
• CONFIG_NAME
• env var
• IDF_VERSION(_XXX) - lazy-load
• SOC_CAPS - lazy-load

after this got merged, shall we release 0.1.0 and add this dependency in idf-build-apps and pytest-embedded?

Sure, let's do it. I will start with pytest-embedded.
