Error installing on Windows 10 Pro

Would anyone out there have some idea on how to install this extension if I have my PostgreSQL installed in Windows?

POSTGRESQL_HOME = C:\Program Files\PostgreSQL\16

But trying to install it using the extracted zip file from this repository, I get this

myuser@my-win-pc MINGW64 ~/Downloads/postgresql-hll-2.18
$ make
makefile:28: C:/Program: No such file or directory
makefile:28: Files/PostgreSQL/16/lib/pgxs/src/makefiles/pgxs.mk: No such file or directory
make: *** No rule to make target `Files/PostgreSQL/16/lib/pgxs/src/makefiles/pgxs.mk'. Stop.

I already tried to edit the actual makefile in the "postgresql-hll-2.18" to properly include the space on the postgresql directory, but it still fails.
