            Bug ID: 199212
           Summary: Script which adjusts include paths in ANGLE's copied
                    headers breaks incremental builds
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Major
          Priority: P2
         Component: ANGLE
          Assignee: webkit-unassigned at lists.webkit.org

Per this discussion on webkit-dev:
https://lists.webkit.org/pipermail/webkit-dev/2019-June/030707.html

and turning on the additional build logging:
defaults write com.apple.dt.Xcode ExplainWhyBuildCommandsAreRun -bool YES

it's clear that the adjust-angle-include-paths.sh script which was added as a build phase in Issue 197755 is causing ANGLE's headers (specifically ShaderLang.h, but soon others) to be modified every time the build runs, causing excessive recompilation.

The necessary fix will be similar to that from Issue 169861.
