Missing dependency declaration with path mapping

[fmeum]

I was testing this out with #23630 applied, I got pretty far but I hit this issue:

ERROR: AsyncRT/BUILD.bazel:138:23: Compiling AsyncRT/lib/Runtime/Globals/Globals.cpp failed: undeclared inclusion(s) in rule '//AsyncRT:RuntimeGlobals.static':
this rule is missing dependency declarations for the following files included by 'AsyncRT/lib/Runtime/Globals/Globals.cpp':
  'bazel-out/cfg/bin/external/gperftools/tcmalloc/include/gperftools/tcmalloc.h'

Where the header here is from a rules_foreign_cc target:

configure_make(
    name = "tcmalloc",
    autogen = True,
    configure_in_place = True,
    configure_options = [
        "--enable-shared=no",
    ],
    copts = [
        "-fPIC",
        "-w",
        "-fexceptions",  # Needed for tests, which ideally we wouldn't build
        "-Wno-register",
    ],
    lib_source = ":all_srcs",
    out_static_libs = ["libtcmalloc_minimal.a"],
    target_compatible_with = select({
        "@platforms//os:linux": [],
        "//conditions:default": ["@platforms//:incompatible"],
    }),
    visibility = ["//visibility:public"],
)

It might be relevant that I access it through an alias (although removing that doesn't help):

alias(
    name = "tcmalloc",
    actual = select({
        "@platforms//os:macos": "@gperftools-macos//:tcmalloc",
        "@platforms//os:linux": "@gperftools//:tcmalloc",
    }),
)

Are you tracking this one?

@keith I added integration test coverage for headers from an external repo, but everything works there. Could you try to build a reproducer for me?

Here's a repro, I didn't try to isolate more than using this rules_foreign_cc target
