Building from source for Windows

[kocio-pl]

Even if this project is no longer maintained, I need a way to compile Mapnik under Windows (needed for new release of Tile Mill), because "Mason runs on both Linux and OS X". The list of dependencies is outdated:

https://github.com/mapnik/mapnik-packaging/blob/master/windows/building_mapnik_dependencies.md

Here are the issues I have found:

Applications and versions

• Visual Studio Community 2017 is available instead of Visual C++ Express
• msysgit is discontinued (now it's Git for Windows)
• libwebp - another page and versions available (strange - now it's 0.6.0 instead of 1.4): https://storage.googleapis.com/downloads.webmproject.org/releases/webp/index.html (https://storage.googleapis.com/downloads.webmproject.org/releases/webp/libwebp-0.6.0-windows-x86.zip)
• zlib - 1.2.11 instead of not available version
• libpng - 1.5.30 instead of not available version
• tiff - 4.0.4 instead of not available version
• gdal - change of directory (now it's in old_releases)
• protobuf - the link has changed: https://github.com/google/protobuf/releases/download/v2.5.0/protobuf-2.5.0.zip

Compilation

• icu - stubdata, common, i18n, layout and layoutex projects need vs2010 - it can be updated, but still compilation does not complete
• jpeg - lack of win32.mak, doesn't work with proposed solution
• libpq - lack of manifest
• tiff - depends on libjpeg, so it doesn't compile too
• libxml2 - problems with macro redefinition
• cairo - depends on zlib
• gdal - doesn't compile
• protobuf - you need to update projects with VSC

I may try with newer versions of these tools and update the documentation, but are there other ways of building Windows port?

@kocio-pl - https://github.com/mapbox/windows-builds should be helpful.

Great, thanks!

I would then add this link in the https://github.com/mapnik/mapnik-packaging/blob/master/README.md and note that Mason is just for Linux and macOS.
