** Presubmit ERRORS **
Missing LGTM from OWNERS of dependencies added to DEPS:
    '+cc/layers/layer_settings.h',

"You need someone from CC because you're adding that as a dependency.  They have to approve you depending on them."

It doesn't explain that you need a CC OWNER LGTM.

More clear message needed. And suggested reviewers.

As clarified by loyso, "You need someone from CC because you're adding that as a dependency.  They have to approve you depending on them." is a message from the chat, not a suggested text.

IMHO, "Missing LGTM from OWNERS of dependencies added to DEPS" is already clear, but perhaps we can make it even more clear by adding

Please ask OWNERs of added dependencies to review this CL.

in the end?

After some further offline discussion with loyso, we think we should change this to:

** Presubmit ERRORS **
You need LGTM from owners of depends-on paths in DEPS that were modified in this CL:
    '+cc/layers/layer_settings.h',
