FD: I do not use debian or any of its derivatives on
any regular basis.  Anything I think I know is probably
at best stale, and possibly wrong.

The number of people building from source is likely
smallish compared to what gets installed via someone
else's packaging.  deb-multimedia, as I understand it,
has an interesting history, and can require careful
configuration to avoid certain issues and anomalies.

Installing anything locally into /usr/local has its own
issues and anomalies of course.

Probably not, but it is also possible no one has
started the process(es) to get nv-codec-headers
into Ubuntu along with ffmpeg.  I have no standing,
but someone who did could look into starting the
process to get those headers packaged for the
good of everyone.

And one could consider creating a PPA now, until
Ubuntu steps up.

Certainly a possibility, but anything you do not need
to carry is likely better.  And if the distro provides the
headers, you should probably prefer them (as
configure now does for a number of libraries)
