Hi,

upstream of libnvme and nvme-cli decided to merge libnvme 2.x and
nvme-cli 2.x back to gether into one source tree as nvme-cli 3.x.

with this, also the library name changed from libnvme to libnvme3. thus,
naturally, libblockdev fails to build as it doesn't detect it in the new
name.

nvme-cli 3.x is current in experimental for you to try. This is a
heads-up as I'd like to upload it soon to unstable (libblockdev is the
only reverse dependency, except for nvme-stas that I maintain too and
has been already updated for nvme-cli 3.x), but of course will wait
until you're "ready".

I've already opened an upstream bug for libblockdev, I'll mark this bug
as forward.

Regards,
Daniel
