# The above has an undesired effect when creating a static library: It forces users to write

# To compile the library, we need the user headers search path (quoted includes) to point to the
# root of the repo, and the system headers search path (angled includes) to point to `include/`.
# Cocoapods effectively clones the repo under `<Podfile dir>/Pods/gRPC-Core/`, and sets a build
# variable called `$(PODS_ROOT)` to `<Podfile dir>/Pods/`, so we use that.
#
# Relying on the file structure under $(PODS_ROOT) isn't officially supported in Cocoapods, as it
# is taken as an implementation detail. We've asked for an alternative, and have been told that
# what we're doing should keep working: https://github.com/CocoaPods/CocoaPods/issues/4386
#
# The `src_root` value of `$(PODS_ROOT)/gRPC-Core` assumes Cocoapods is installing this pod from
# its remote repo. For local development of this library, enabled by using `:path` in the Podfile,
# that assumption is wrong. In such case, the following settings need to be reset with the
# appropriate value of `src_root`. This can be accomplished in the `pre_install` hook of the

# Like many other C libraries, gRPC-Core has its public headers under `include/<libname>/` and its
# sources and private headers in other directories outside `include/`. Cocoapods' linter doesn't
# allow any header to be listed outside the `header_mappings_dir` (even though doing so works in
# practice). Because we need our `header_mappings_dir` to be `include/grpc/` for the reason
# mentioned above, we work around the linter limitation by dividing the pod into two subspecs, one
# for public headers and the other for implementation. Each gets its own `header_mappings_dir`,
# making the linter happy.
