libmariadbd19 was intended to be added as the package that
included the libmysqld shared library. This was missing
from the debian control file.

The libmariadbd-dev package requires libmariadbd19 to provide
the shared library.

The shared libraries for embedded mysql will go into the libmariadbd18
package rather than the libmariadbd-dev development package.

/usr/bin/mariadb_config is a executable that assists embedded developers
to use the correctly correct header and library files during their
development.
