Builds on #370 .
I'm working on packaging for vcpkg (see microsoft/vcpkg#24310 ) and I noticed that their maintainer guide recommends not allowing Windows shared library builds for libraries with CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS. I thought it would be easy to add export declarations, since there's a clear separate API header. However, it turns out that several examples and tests use nominally "internal" APIs, so in most cases I added additional export defines just to highlight those semi-public APIs. (One usage of a private API is called out in a comment, so that build I just disabled when building for shared libraries).
Curious what you would like to do about those. We could also go to a linker version script/.def file instead of the defines if you prefer. This is mostly a request-for-comment, though I certainly wouldn't mind if it got merged.
