[geos-devel] Compiling geos on windows

[Daniel Baston]

Hi Paul,

I suspect you're running into the same problem documented in this ticket:
https://trac.osgeo.org/geos/ticket/975
I think the CI builds are succeeding because they have
-DBUILD_SHARED_LIBS=NO.

We probably need to build shared libraries in the CI builds. I haven't
fixed it because I don't have ready access to Windows or Visual Studio.
If you're able to submit a PR to fix this, it would be most welcome.

Thanks,
Dan
