Hello,
I had some luck in packaging vst3sdk. I pushed my packaging attempts
(just the debian/ directory) to my personal repository on salsa [1]. The
package builds and installs VST3 plugins, debian/copyright is as well
almost finished.
I had some difficulties in constructing the multiple upstream tarball
(MUT). uscan does not seem to be able to handle debian/watch correctly,
thus I first have to change upstream version to 0 in debian/changelog,
run 'uscan --download', revert the upstream version in debian/changelog
and run it again. From downloaded tarballs the MUT is built by
debian/get-orig-source. I plan to import the constructed MUT into the
same git repository [1] to simplify its usage, but I will probably
exclude doc/ subdirectory due to multiple source-is-missing problems.
