The proper fix is modifying libspatialite IMO.
Please confirm if there is an issue with libcurl.
I do not like to see uncertainty being made public and fixes being made
private.

All,
Thank you for the suggestions. And to clarify: yes this is an MSVC
build so -fvisibility=hidden is not an option. I am currently
investigating adding a def file to curate the symbols exported by the
gdal dll. I removed the decorated symbols and built. The resulting dll
still reports the decorated symbols, but I'm hopeful that this is
expected behavior. I'm going to attempt to remove the libspatialite
symbols from the def file and rebuild,

In vcpkg, x64-windows means MSVC.
And even in the visibility world, you can find libs that get it
wrong when the attention is exclusively on shared libs.
(Studying the proposed libspatialite patch, I believe I spotted
different defaults for visibility in different chunks. Needs more
investigation...)

Hi,
All symbols that aren't specifically exported should be
hidden if when you build the flag "-fvisibility=hidden" is
set. See cmake/helpers/configure.cmake.
I don't think this will help with MSVC and its dllexport
declarations.
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.
This may be helpful:
