CJSON_HIDE_SYMBOLS - Define this in the case where you don't want to ever dllexport symbols
CJSON_EXPORT_SYMBOLS - Define this on library build when you want to dllexport symbols (default)
CJSON_IMPORT_SYMBOLS - Define this if you want to dllimport symbol
For *nix builds that support visibility attribute, you can define similar behavior by
setting default visibility to hidden by adding
-fvisibility=hidden (for gcc)

-xldscope=hidden (for sun cc)
to CFLAGS
then using the CJSON_API_VISIBILITY flag to "export" the same symbols the way CJSON_EXPORT_SYMBOLS does
