fast-deps is fast when deps log exists, but it would miss exec cache due to difference of action inputs between fast-deps vs scandeps. Use no-fast-deps (i.e. scandeps) to expect high cache hit rate.

About
//build
contains:
- Core GN templates and configuration
- Core Python build scripts
Since this directory is DEPS'ed in by some other repositories (webrtc, pdfium,
v8, etc), it should be kept as self-contained as possible by not referring
to files outside of it. Some exceptions exist (//testing
, select
//third_party
subdirectories), but new dependencies tend to break these other
projects, and so should be avoided.
Changes to //build
should be landed in the Chromium repo. They will then be
replicated to the stand-alone build repo
by the gsubtreed tool.
Note: You can find all directories already available through gsubtreed in the
list of all chromium repos.
