Dear Martin,

Plus one more question. I tried running the tests (again, from the
standalone version rather that from the distributed one) to make sure
that there are no negative consequences of linking the binary against
libc++ while the rest links against libstdc++ (this is usually not a
problem if libraries don't have the C++ API).

My question: is it considered an overkill to include google code in
your sources? It's not exactly clear to me how this FAQ applies:
    https://github.com/google/googletest/blob/master/googletest/docs/FAQ.md#why-is-it-not-recommended-to-install-a-pre-compiled-copy-of-google-test-for-example-into-usrlocal

and if there is some simple way to automate the tests (without me
having to go through all the steps of manually fetching and compiling
gtest each time; I would love it if simply "make test" worked out of
the box). See also:
