That is definitely true. Automake puts together the makefile rules for you but of course it still works in the same way in the end.

I've also found this guide to be pretty helpful in the getting into the basics: https://autotools.io/index.html <https://autotools.io/index.html>

Yeah and that's largely due to the current layout being recursive, ie. multiple makefiles in multiple directories. This is one of the reasons there have been some projects that rework things into a single main makefile as it lowers the amount of directory walking and intermediate steps ie. non-recursive make: https://autotools.io/automake/nonrecursive.html <https://autotools.io/automake/nonrecursive.html>

To some degree, configure will always be slow for all sorts of reasons, but there are definitely techniques to slow down the make process. Another advantage to non-recursive make is that doing a parallel build would work without timing uncertainties between different makefiles.
