meson: nm_runstatedir can't be configured
autotools introduced runstatedir
and nowadays it's suggested to set that to /run
so the runtime directory will end up as /run/NetworkManager/
.
E.g. in the Debian package I currently use autotools and I'm passing --runstatedir=/run
as one of the build flags.
meson has no official runstatedir equivalent afaik, so I'd suggest introducing a variable that can be set via -D
.
