`corelgilua51` not found in lgi lua

I am trying to run the following code

local lgi = require("lgi")
local Gdk = lgi.Gdk
local Gtk = lgi.Gtk

Gtk.init()

-- Create a new window
local window = Gtk.Window({
    title = "LGI Test Window",
    default_width = 300,
    default_height = 200,
    on_destroy = Gtk.main_quit,
})

-- Create a label and add it to the window
local label = Gtk.Label({ label = "Hello, LGI!" })
window:add(label)
window:show_all()
Gtk.main()

But this is giving me the following error

lua: /home/username/.luarocks/share/lua/5.3/lgi/core.lua:14: module 'lgi.corelgilua51' not found:
    no field package.preload['lgi.corelgilua51']

I have already set LUA_PATH and LUA_CPATH, but installing lgi from luarocks does not have the corelgilua51, what could be the issues, the lgi only contain the following files:-

drwxr-xr-x. 1 username username   226 Nov 15 13:01 .
drwxr-xr-x. 1 username username    30 Nov 15 13:05 ..
-rw-r--r--. 1 username username 15928 Nov 15 13:01 class.lua
-rw-r--r--. 1 username username 11130 Nov 15 13:01 component.lua
-rw-r--r--. 1 username username   761 Nov 15 13:01 core.lua

-rw-r--r--. 1 username username  1090 Nov 15 13:01 log.lua
-rw-r--r--. 1 username username  6217 Nov 15 13:01 namespace.lua
drwxr-xr-x. 1 username username   524 Nov 15 13:01 override

-rw-r--r--. 1 username username  7088 Nov 15 13:01 record.lua
-rw-r--r--. 1 username username    15 Nov 15 13:01 version.lua

lua version 5.3.6, not upgraded to 5.4 as a project I am trying to use requires a lua version less than 5.4, how can a module be absent when installing from luarocks and any help would be appreciated. Please ask for any other information if required.

The reason for this question is that the lib directory in the lgi's Makefile is hardcoded as /usr/local/lib/lua/5.1.

PREFIX = /usr/local
LUA_VERSION=5.1
LUA_LIBDIR = $(PREFIX)/lib/lua/$(LUA_VERSION)
LUA_SHAREDIR = $(PREFIX)/share/lua/$(LUA_VERSION)
...
mkdir -p $(DESTDIR)$(LUA_LIBDIR)/lgi
cp $(CORE) $(DESTDIR)$(LUA_LIBDIR)/lgi

As you can see in the question, when you use it in another version of Lua, the directory it searches for is /usr/local/lib/lua/5.3/lgi.so, which resulted in the error. The solution can be to modify the value of LUA_VERSION in the Makefile, or copy the output file to the correct directory, or change package.searchpath.
