I tried to adjust the Ubuntu v4l-utils development scripts on top of the
ariel/mesonbuild-v4 git branch.

On Unbuntu 20.04 I did the following:

mkdir v4l-meson
cd v4l-meson
git clone https://gitlab.com/adalessandro/v4l-utils.git
git clone https://git.launchpad.net/\~libv4l/+git/v4l-utils-packaging
cd v4l-utils
git checkout ariel/mesonbuild-v4
ln -s ../v4l-utils-packaging debian
cd debian
git checkout meson-build
cd ..
dpkg-buildpackage -uc -b -rfakeroot # install build-essential + missing

I noticed the following:
* library symlinks are not in place
   see https://packages.debian.org/sid/amd64/libv4l-0/filelist

* static libraries are missing

* bfd sources did not compile properly (now disabled in my repo):
