This answer https://emacs.stackexchange.com/questions/28981/finding-files-by-names mentions
"If you are running Dired with a 'ls' implemented in elisp, 'ls-lisp' or 'eshell-ls', then you can recursively list all the files matching a wildcard".
But I do not know how to achieve that.
Is there a way (customization or setting in init.el) to ask dired to use eshell commands where available?
