Trouble with Lazarus/ZeosDB with pipes, so how to now build libmysqld.dll?

I have tried:

mysqld.exe --skip-networking --enable-named-pipe --named-pipe=<some-unique-name>
and connecting via libmariadb.dll, via this named pipe <some-unique-name>.

But as I am using ZeosDB under Lazarus (64bit) naming a pipe does not seem to be an option.

So I have returned to trying the Embedded dll soluton and ...
– Previously ...

cmake . -DWITH_EMBEDDED_SERVER=1 && cmake --build . --config relwithdebinfo --target libmysqld

As per https://jira.mariadb.org/plugins/servlet/mobile#issue/MDEV-15100/comment/106350
would build libmysqld.dll and you would find it in

 libmysqld\RelWithDebInfo directory

How now do we build libmysqld.dll?

Or is it completely depreciated (-- but still very useful/needed sometimes!)
