--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

-D bash_completion=false: Use this option if the external bash-completion package is not installed.

-D qrtr=false: This switch disables support for the QRTR protocol which needs the external libqrtr-glib package.
