--- Comment #37 from Maarten Hoes <hoes.maarten at gmail.com> ---
Well, I finally got around to testing this, and the '--exclude' option seems to
work as expected. If you run 'scan-build' with (among others) these options :

--exclude $src/*/UnpackedTarball/* --exclude $src/workdir/* --exclude
$src/instdir/* --exclude $src/external/

then the 3th party code does not end up in the final report.

So you can now run ./autogen with '--without-system-libs
--without-system-headers' so you get the needed packages in the right versions
during the build, and in combination with the mentioned '--exclude' options
without them ending up in the final report. You do need clang9 (or newer)
though, older versions do not have the '--exclude' option for scan-build.
