# NOTE
#   The build systems of axc (ex-libaxolotl)
#   at https://github.com/gkdr/axc and of libomemo
#   at https://github.com/gkdr/libomemo build static
#   libraries (*.a files) only, so it is not clear when or
#   how to best unbundle them into standalone packages.
#   Related yet-to-be-merged pull requests to build shared libraries
#   exist upstream:
#   - https://github.com/gkdr/axc/pull/17
#   - https://github.com/gkdr/lurch/pull/151
#   - https://github.com/gkdr/libomemo/pull/30
