ABSL_OPTION_USE_STD_STRING_VIEW is used to enforce this: 0 or 1 to enforce absl::string_view or std::string_view respectively, or 2 to base it on the available C++ standard. At least on my build from pkgsrc, it's set to always use absl::string_view:

Yes, because pkgsrc abseil is built with FORCE_CXX_STD=c++14.

> I'm wondering if qtwebengine-everywhere is including the abseil and re2 headers in the chromium tree, which does set ABSL_OPTION_USE_STD_STRING_VIEW=2 (src/3rdparty/chromium/third_party/abseil-cpp/absl/base/options.h).

And yes it is, which is why we need to use the bundled re2.
