I'm attaching the patch I'm using as krita-5.1.0-xsimd.patch, maybe I did
something wrong, with it applied I get the following error:

In regards to what tomtomtomreportin...@gmail.com just posted I want to note
that we currently compile our xsimd package with xtl support disabled by
passing -DENABLE_XTL_COMPLEX:BOOL=FALSE since we didn't package
https://github.com/xtensor-stack/xtl yet.
