My days of wrestling with libtool/autoconf/automake/cmake are mostly
in the past. On FreeBSD/MacOS I use pkg/brew. For any new coding I
mainly use Go. Even cross compiled binaries just work. It has a very
well engineered ecosystem.

I agree with this. auto{conf,make}/configure is just the wrong approach.

At Real Networks our media server ran on 12 or so Unix platforms + windows +
macOS9 (at the time). I managed to corral machine dependent code in basically
a couple files for all but MacOS9. No #ifdefs in any other file. C++ also
helped to hide things like select(2) vs poll(2) from other code.
