That last "empty" -I might be the problem. It seems like the FFTW include location isn't being found. What do you get if you run `pkg-config --cflags fftw3f` on the...

Given what you got with the pkg-config command, I think that that "empty" -I should have been -I/usr/local/include. You could try manually setting that in the makefile for FFTINC. The...

@vtonder Thanks for that. I've changed the ordering in the official PRESTO even though I have *no idea* why that works. Seems really bizarre to me....

Adding @NickSwainston to this since I'm a Docker noob. I'm playing around with it now, though,

Ah-ha... I think I see the issue. My system is running Ubuntu 21.04, but the Docker build is for Ubuntu 20.04. During the build, docker saw that my PRESTO C-libraries...
