<absl/**/*.h> vs "absl/**/*.h"

[phaedon]

I'm using the Bazel central registry to include an absl dependency in my project:
bazel_dep(name = "abseil-cpp", version = "20230125.1", repo_name = "com_google_absl")

Why do the include statements require the use of quotations rather than angle brackets? This is surprising since it is an external library.

#include <absl/flags/flag.h>  // This fails to compile with "No such file or directory"
#include "absl/flags/flag.h"  // This compiles

Am using a statement like this to run:
bazel run :myproject --enable_bzlmod --cxxopt=-std=c++20

as a followup, I see that

https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#sf12-prefer-the-quoted-form-of-include-for-files-relative-to-the-including-file-and-the-angle-bracket-form-everywhere-else

and

https://bazel.build/docs/bazel-and-cpp#include-paths

may be recommending a different convention.
