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

setting default visibility to hidden by adding

-fvisibility=hidden (for gcc)

-xldscope=hidden (for sun cc)
