I think that just supports my argument, really. I've never really used makefiles. The blog post talked about using patsubst to change a path. The name of the function essentially gives no clue at all what it does.
Isn't that the problem with using blog posts as educational sources?
(I'm happy I was learning all my toolkit long before blogs became a thing. It's hard to open and read Physics book, when someone on YT talks funny about its second chapter.)
