Minor missing symbol apache::thrift::GlobalOutput for Windows shared library build

Current trunk has a minor problem when creating a shared library build with cmake on Windows with MSVC 2015 and MSVC 2017. It seems one of the symbols is not defined, even when 
CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS is on:

TZlibTransport.cpp.obj : error LNK2001: unresolved external symbol "class apache::thrift::TOutput apache::thrift::GlobalOutput" (?GlobalOutput@thrift@apache@@3VTOutput@12@A)
bin\thriftzmd.dll : fatal error LNK1120: 1 unresolved externals

I don't know why this symbols fails for cmake. But if you want to go another route with explicitly exporting all relevant classes, and you need help to create a cmake-based dllimport/dllexport-integration, I can offer some help.
