I'm happy to be able to announce release of Visual Studio 2015 projects and solutions to build GTK+, GTKmm, all it's dependencies as well as few other popular "hard to build" C/C++ libraries.
Most of the projects have configurations to build either DLL's or static libraries, in addition
you can choose whether to link against all dependencies or only required ones.
Also there is a plenty of test projects within solutions to perform tests against each DLL/LIB after successful compilation and recompile as needed possibly with different settings.
Although work is still in progress to automate the entry build process.
Yes, I'll definitely make a post on hacker news, thanks for suggestion!
