- - You will need bmusb from testing or unstable; stretch only has 0.5.4.
+ libprotobuf-dev libsqlite3-dev meson libjpeg-dev
- - You will need a Meson backport; the version in stretch is too old.
+Exceptions as of December 2018:
- Debian does not carry CEF (but it is optional). You can get experimental
(and not security-supported) CEF Debian packages built for unstable at
