I am new to bazel, but I want to release a library to other with headers and shared library.

My code tree likes this(but more subdirectories) :

root

• feature1
  • feature1.hpp
  • feature1.cpp
  • BUILD
• feature2
  • feature2.hpp
  • feature2.cpp
  • BUILD
• feature3
  • feature3.hpp
  • feature3.cpp
  • BUILD
• BUILD

I want to package a tar.gz file in the root BUILD with lib and include,

cc_binary(
    name = "feature_impl",
    deps = [
       ":feature1",
       ":feature2",
       ":feature3",
    ],
)

cc_binary(
    name = "feature",
    linkshared = True,
    deps = [":feature_impl"],
)

filegroup(
    name = "headers"
    srcs = XXXXXXX
)

pkg_tar(
    name = "headers_pkg"
    srcs = "headers",
    package_dir = "include",
)

pkg_tar(
    name = "feature_pkg"
    srcs = ":feature",
    package_dir = "lib"
)

How can I package all the headers with sub directores structures ??
Now I have to write a pkg_tar target in the BUILD of every subdirectory.

Is there a rule like "sub_glob" for filegrouop?
