I've been getting my hands dirty with CMake in recent weeks, and I now firmly believe that's the way to go with respect to a Windows build system for TigerVNC. I don't propose replacing autotools (at least for now), but CMake allows one to generate their own build system based on NMake or Visual Studio projects or even MinGW, and it works with 64-bit. People can still use MinGW and autotools to build TigerVNC if they want, but this gives native Windows developers a viable option for working with our code that doesn't require compiler customizations.
The intermediary step is for me to implement a CMake system for Windows builds of libjpeg-turbo, and adding the system to TigerVNC should be straightforward after this is done. Since this is currently unfunded work, I can't give a timeframe as to when I might be able to complete it, but I believe that it needs to be part of 1.1.
