If you're experienced you'd download and install all the dependencies, perhaps via "/opt", where a local package-manager would not interfere.

But honestly? If you're new to using Linux then you should use the supported approach by your system. If you're running Debian, for example, "apt install emacs". If you're running CentOS "yum install emacs".

Trying to do things outside the confines of the package-manager seems like an odd-constraint. I can appreciate it might make some sense, but when there are so many dependencies installed - fetching/building/installing them all one at a time is going to be very fiddly and annoying, even for a somewhat-experienced user.
