[pdal] unresolved external symbol in examples/writing (VS 2015)

[massoud pourmandi]

when I build an example of PDAL library I'm getting following errors, it is
originated from Extractor.hpp and Insertor.hpp. did I miss something with
I'm building PDAL project?. I used OSGeo4W64 for downloading dependencies.
I would appreciate any help, thanks in advance.
