Could you add an entry to the DEVELOPERS file ?

You should not use BR2_PACKAGE_EUDEV, but BR2_PACKAGE_HAS_UDEV, so that
either eudev or systemd can be used as a udev provider. However, udev
is not a mandatory dependency, so in fact this dependency is not needed.

Please document why this is needed in a comment. If I get it correctly,
it's because casync uses scandirat(), which is not implemented by
current versions of musl and uclibc-ng.

This dependency is not mandatory.

This dependency is not mandatory.
Also, there's an optional dependency on zlib.

+= not needed, just use = here. xz and zstd are not mandatory
dependencies. You also need to handle zlib as an optional dependency.
Hint: pass -Dliblzma=disabled -Dlibz=disabled -Dlibzstd=disabled.
Note that to handle udev as an optional dependency, there is a bug.
Even if you pass -Dudev=false it still tries to query pkg-config about
udev, due to a bug in meson.build. It would be good to fix the bug in
meson.build. I just worked around the problem by passing -Dudev=false
-Dudevrulesdir=blah.

I think everywhere else in meson packages we use lower-case "true" and
"false".

Mistake here in the option name.
