--- Comment #1 from Aleksei Bavshin <alebastr89@xxxxxxxxx> ---
Some things to address before formal review:

> License:  ISC

ISC and MIT and Unlicense (with comment about bundled miniz)
Also, `Provides: bundled(miniz) = 2.1.0` with a comment that it's already
removed in upstream master.

> BuildRequires: cmake

Not necessary, all dependencies are shipping pkgconfig files. CMake is only
required when you know that there's dependency that does not have pkgconfig
file but provides cmake modules.

> %files
> %{_libdir}/lib%{name}.so.*

Please, specify at least one element of SONAME to avoid unnoticed incompatible
SONAME changes[1]. I.e. %{_libdir}/lib%{name}.so.0* 

> %{_includedir}/*

I'd prefer this to be more specific, but that's just nitpicking.

It's better to remove that from meson.build with downstream patch. Upstream
issue[2] mentions that at least x86_64 works fine without -mavx, although it
does not specify if there's any noticeable performance loss.
IIRC, Fedora baseline for x86_64 is K8 (no avx support) and for ARM - hardware
without neon instruction set support. I could be wrong about ARM, but it's
still better to keep optimization limited to distribution-wide optflags.
