cmake: Permit consuming target transitive dependencies (possibly modern CMake interfaces)?

[EricCousineau-TRI]

Is it possible to have cmake_external (or some other target) support consuming transitive deps of a target? If possible, can it be taught to consume CMake Interface Libraries?

I tinkered with a version of cmake_external, but couldn't make it work for my intended use case, which is to consume the includes + libs of CMake targets. My hack-and-slash attempt (coupled with Python bits - sorry for the mess!):

ros2_bazel_prototype:

• Overview
• colcon.bzl - repo rule definition
  • cc_ament_CMakeLists.txt.in - template CMakeLists
  • build.py.tpl - Python repo generating script (was too lazy to prototype Skylark for this hacky functionality...)
• ros2 - usage of colcon_repository

More background: colcon/colcon-bazel#14
