<div>All symbols that aren't specifically exported
should be hidden if when you build the flag

I don't know that this is MSVC. I thought it was a GCC build
on Windows, but regardless, things are essentially the same
(on Windows you *must* export all the symbols you want
visible). I don't know spatialite, but there should be some
sort of DLL marker (like CPL_DLL in GDAL) that can be turned
off when building a static library that you then link into
GDAL.<br>
