Run lv2config.

No.  Plugins are not extensions.  They all live in bundles, though.  All
bundles are typically in PREFIX/lib/lv2 or ~/.lv2

Indeed.  Do it.

It builds the include directory tree so includes like:

#include "lv2/lv2plug.in/ns/ext/event/event.h"

work.

You don't really need a deep understanding of what is going on, only
that you must run lv2config after installing an extension to compile
against it.
