crashpad/build/chromium_compatibility/README.crashpad

This directory is used as a secondary GN source root for compatibility with
Chromium. Files in this subtree should match file paths that the Crashpad build
files need to refer to when building in Chromium. In the Crashpad tree, they
should either be empty/no-ops, or forward to the real Crashpad implementation
in the real tree. No actual configuration should be done in this secondary tree.
Rework GN files to start to support building standalone, and also in Chromium - Adds a .gn and a build/BUILDCONFIG.gn that uses mini_chromium's build/BUILD.gn. - Adds some stub BUILD.gn files in locations where Chromium expects them (in //build, //testing, //third_party) containing empty targets/configs. These are no-ops in standalone builds, but add functionality when building in Chromium. This is in preference to having a global bool that conditionally does Chromium-y things in the Crashpad build files. These stub files are all contained in a secondary source root in build/chromium_compatibility, referred to by //.gn. - Adds //base/BUILD.gn which forwards to mini_chromium/base. This is only used when building standalone so that both Chromium and Crashpad can refer to it as "//base". - Changes references to other Crashpad targets to be relatively specified so that they work when the root of the project is //, and also when it's //third_party/crashpad/crashpad as it is in Chromium. - Moves any error-causing Mac/Win-specific files into explicit if (is_mac) or if (is_win) blocks as part of removing the dependency on set_sources_assignment_filter(). As yet unresolved: - CRASHPAD_IN_CHROMIUM needs to be removed when standalone; to be tackled in a follow up. - Not sure what to do with zlib yet, the build file currently assumes "in Chromium" too, and similarly having Crashpad //third_party/zlib:zlib pointing at itself doesn't work.
