Mostly correct. The built library contains a full static build of sqlite
and spatialite amalgamated. The resulting binary is linked dynamically to
proj and geos. So you need to have proj and geos installed on the system.
The reason we amalgamate the spatialite build rather than dynamically link
to it is to avoid conflicts between the sqlite already installed on the
system and the one bundled internally by xerial.
Thinking about the whole mess it would probably just be easier to strip out
the internal sqlite used by the xerial driver and completely rely on
dynamic linking.
