I am installing Spatialite for use in GeoDjango on a Windwos 10 64 bit system. I have already installed GEOS, PROJ, and GDAL from source in my command prompt. As spatialite requires using nmake on windows, I am using the Visual Studio 2017 command prompt to build it, however, in the README for libspatialite 4.2.0 it states that
> cd c:\libspatialite-3.1.0
> nmake /f makefile.vc
> nmake /f makefile.vc install
Please note: standard definitions in 'makefile.vc' assumes:
- enabling PROJ
- disabling GEOS
If you want to alter the default behaviour then make modifications in
'makefile.vc'. Also note that 'libspatialite-geos.def' contains those external
symbols to be exported from the DLL when you build GEOS.
as I am using GeoDjango for geographic queries I think that GEOS will be necessary. How can I enable GEOS in the makefile.vc? It doesn't seem clear to me how to do that. For convenience, here is the full makefile.vc below.
