Add a new pugixml static library project and include it in the solution to support ARM builds. pkgread now references the new pugixml project (removed direct pugixml file/includes) and its Release|ARM PrecompiledHeader is set to NotUsing. Update solution configurations to include pugixml and add appropriate build platform mappings. Update notes/symlinks.md with instructions for the new project and manual copying of generated pugixml.lib; also clear an AdditionalLibraryDirectories entry in priformatcli.
