Processed 11472 nodes.
Error: There are 21 missing dependency paths.
21 targets had depfile dependencies on 14 distinct generated inputs (from 1 rules) without a non-depfile dep path to the generator.
There might be build flakiness if any of the targets listed above are built alone, or not late enough, in a clean output directory.
After a clean reconfigure (no build):
