          ^---------------------------------------------
The target:
  //chrome/installer/setup:lib
is including a file from the target:
  //third_party/crashpad/crashpad/util:util
It's usually best to depend directly on the destination target.
In some cases, the destination target is considered a subcomponent
of an intermediate target. In this case, the intermediate target
should depend publicly on the destination to forward the ability
to include headers.
Dependency chain (there may also be others):
  //chrome/installer/setup:lib -->
  //components/crash/content/app:app --[private]-->
  //third_party/crashpad/crashpad/util:util

I'm reverting the CL. The fix should not be too hard but I don't want to rush this.

Hmm there's a merge conflict. Looking into fix.

 Issue 880488  has been merged into this issue.

Merge conflict arises from:
https://chromium-review.googlesource.com/c/chromium/src/+/1200942

Behavior is reproed by
  gn gen out/Release --check


I tried to change setup/BUILD.gn to tweak
  "//third_party/crashpad/crashpad/client"

inclusion in various ways, but still see problem.

Cannot find quick fix, so going with double-revert:

(First) https://chromium-review.googlesource.com/c/chromium/src/+/1200942
(Then)  https://chromium-review.googlesource.com/c/chromium/src/+/1200862

(deleted comment #5 got order wrong).

Thanks Sam. That's the best course of action. I appreciate the quick response!

NP, everything's in now!
