Well, it was nice of him to send you a blog link, rather than telling you to buy his book, which mentions this exact trick :) https://www.nostarch.com/gnumake

  Many of the things in my book are on line in different places. The technique I use in the book is here: https://www.cmcrossroads.com/article/makefile-optimization-eval-and-macro-caching https://www.cmcrossroads.com/article/makefile-optimization-e... It uses a different technique and requires replacing $(FOO) with $(call cache,FOO) everywhere. The book comprises everything I've written about GNU make edited, rechecked and cleaned up with additions to cover new GNU make features and a couple of other things I hadn't written before.

    If you start asking him too many questions he does eventually just throw the book at you (albeit a free autographed copy).
