The 2.5.0 version of libodb-mysql supports both MySQL and MariaDB and
there is a configuration variable to select which client library to
use.

The magic incantation (which will hopefully make more sense once you
go through the setup steps) will look like this:

$ bpkg build config.libodb_mysql.client_lib=mariadb -- \
    libodb-mysql ?sys:libmysqlclient ?sys:libmariadb

Or, if you want to try to build libmariadb from source (we have
known-to-build packages for both MySQL and MariaDB), then:

$ bpkg build config.libodb_mysql.client_lib=mariadb -- \
    libodb-mysql libmariadb ?sys:libmysqlclient

(That ?sys:libmysqlclient is currently necessary because we don't yet
have conditional dependencies in the package manager so libodb-mysql
unconditionally depends on libmysqlclient even though at the build
system level one can select between different client libraries. But
that support is coming in the next version of build2).
