# Note that tests which depend on internal (not public) APIs are not
# enabled unless a static library is built.  This is because on some
# systems (e.g. Windows) we do not expose symbols that are not in the
# public API. (When CMake learns more about using mapfiles to suppress
# symbol visibility we will do this even more, to protect the namespace
# of the user.)
