So when trying to get this to build for ros2/rcl#327, I realized that the log4cxx dependency isn't readily satisfiable on all of the platforms that we expect to support, causing build failures (ros2/rcl#327 (comment)).

For Ubuntu Linux, this should be relatively easy to add, because it is available through apt, but in order to get this out for ros2, we'll need to get those dependencies available on MacOS and Windows as well (especially for making something as core as rcl or rcutils depend on it).

For Windows, the best approach would be to have a choco package available (which there is currently not), or alternative provide a vendor package, as we have choosen to do for various other dependencies.
