Wt

Using pre-built libraries for Html->Pdf causes linker errors with Installing_Wt_on_MS_Windows.

Bug reproducible with;

• Wt-3.3.5 and Wt-3.3.6 on Visual Studio 2013 or Wt-3.3.6 on Visual Studio 2015
• HPDF_DLL defined
• Linking libhpdfd.lib, wtd.lib, wthttpd.lib, wtdbod.lib, wtisapid.lib, wttestd.lib in Debug Build
