Since this configuration option is going to be distro-independent (and
possibly architecture independent) I would suggest the build process
could be patched to handle this by reading the kernel configuration;
grep 'CONFIG_HZ=' /boot/config-$(uname -r) | cut -f 2 -d '='
The above line returns the HZ value for the kernel performing the build
which (I would guess) would match the configuration used by the kernel
on any machines running the distribution?
Ideally this would be handled at run time, but I'm not aware of a
cross-distro syscall that can read the kernel's HZ value.

Dear Maintainer,
cpulimit(1) says
The current version of cpulimit assumes the kernel HZ value 100.
but
$ grep ^CONFIG_HZ /boot/config-*

/boot/config-6.1.0-27-amd64:CONFIG_HZ=250

/boot/config-6.1.0-35-amd64:CONFIG_HZ=250
and
/boot/config-6.5.0-3-amd64:CONFIG_HZ_250=y
/boot/config-6.5.0-3-amd64:CONFIG_HZ=250
/boot/config-6.7.7-amd64:CONFIG_HZ_250=y
/boot/config-6.7.7-amd64:CONFIG_HZ=250
and
/boot/config-6.17.13+deb14-amd64:CONFIG_HZ_250=y
/boot/config-6.17.13+deb14-amd64:CONFIG_HZ=250
So this hasn't been correct since at least bookworm,
and still isn't in sid.
Best,
