The BSD patches for 14.0 are ready for GIT checkin (next time I boot the desktop). I tested on Debian 9.1 32-bit and Ubuntu 16 and of course, Fedora 32 -- just because even though they are mostly specific to only BSD, it is just a lot easier to find a problem now then having to backtrack later.
P.S. this problem "Fix for freebsd 14 build OpenEXR /// cflags pkg-config does not work for some reason/" is, I believe, the reason why I could never get OpenEXR upgraded from 2.4.1 to 3.1.4 as provided by Manuel V. I could not get "without openexr" working for Ubuntu 16 which has a too low version default of cmake.
