Yes, I am aware of this, and I do take additional care to make sure that things work as expected. Still, thanks for mentioning this, and see below... > Using CMake instead of make has caused some interesting issues in the past. > The first that comes to my mind happened in Arch Linux, and got featured on > the Phoronix news site: > <https://www.phoronix.com/news/Arch-Linux-Bizarre-Zstd> Right... thanks for reminding me of that! I had indeed noticed a couple of days ago that the CMake build differed in a couple of minor ways from the Makefile one and I had made a mental note to fix that... and then I forgot. There were two main differences: legacy support and setting the C standard. The former is now handled via a CMake config option passed via `dh_auto_configure`, and the latter is disabled with a patch taken from the upstream development branch, although in my (limited) testing there was no effect on the compression speed, at least with the GCC version in Debian unstable as of now.
