warning C4251 (appVeyor)

[cvvergara]

Annoying warning from a "stupid compiler"

c:\projects\geos\include\geos\precision\minimumclearance.h(32): warning C4251: 'geos::precision::MinimumClearance::minClearancePts': class 'std::unique_ptr<​geos::geom::CoordinateSequence,std::default_delete<_Ty>>' needs to have dll-interface to be used by clients of class 'geos::precision::MinimumClearance' [C:\projects\geos\src\geos.vcxproj]

c:\projects\geos\include\geos\triangulate\quadedge\quadedgesubdivision.h(96): warning C4251: 'geos::triangulate::quadedge::QuadEdgeSubdivision::quadEdges': class 'std::vector<​geos::triangulate::quadedge::QuadEdge *,std::allocator<_Ty>>' needs to have dll-interface to be used by clients of class 'geos::triangulate::quadedge::QuadEdgeSubdivision' [C:\projects\geos\src\geos.vcxproj]

Basically it shows on identifiers for stl stuff like vector, unique_ptr etc
