If you are compiling from git, make sure to run `git submodule update --init --recursive' or call autogen.sh, which will invoke that command for you.

Official releases are on https://github.com/quixdb/squash/releases and are the ones labeled \"squash-plugins-extra-x.y.z.tar.bz2\", not \"Source code\".  GitHub is aware of the issue.")
