Error while building Geos Release 3.13.0 in Visual Studio for platform toolset "Visual Studio 2017(v141)"

Following error while building geos Release 3.13.0 in Visual Studio for platform toolset "Visual Studio 2017(v141)"

[exec] C:\geos-3.13.0\dist\include\geos/operation/relateng/TopologyPredicate.h(197): error C2679: binary '<<': no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)

This seems to build OK when platform toolset "v143"

This file TopologyPredicate.h seems to be introduced in latest release only

Have a patch that works? I don't have that env here, and the code in question looks pretty anodyne.

I found a similar issue on SO here.

It recommends adding

#include <string>

(and maybe some other standard headers).

@psharma-gdal Can you try this and see if it fixes the problem?

As this is a std::ostream related operator, I believe this should rather be:

#include <ostream>
