This is necessary to make the Meson one the default and preferred one. Co-authored-by: Robert Hensing <roberth@users.noreply.github.com>

Building Nix from Source
Nix is built with Meson. It is broken up into multiple Meson packages, which are optionally combined in a single project using Meson's subprojects feature.
There are no mandatory extra steps to the building process: generic Meson installation instructions like this should work.
The installation path can be specified by passing the -Dprefix=prefix
to configure. The default installation directory is /usr/local. You
can change this to any location you like. You must have write permission
to the prefix path.
Nix keeps its store (the place where packages are stored) in
/nix/store by default. This can be changed using
-Dstore-dir=path.
Warning
It is best not to change the Nix store from its default, since doing so makes it impossible to use pre-built binaries from the standard Nixpkgs channels — that is, all packages will need to be built from source.
Nix keeps state (such as its database and log files) in /nix/var by
default. This can be changed using -Dlocalstatedir=path.
