Dear Eduard, dear Inkscape Team I would think that CMake allows newer versions than the specified one, unless explicitly told otherwise. The issue here is that some GTK 3.16 are actually used although only GTK 3.8 features should be used (as far as I understood). I have some experience with creating build systems which use specific package versions based on Cygwin. Since there is a working MSys build, it shouldn't be difficult to build with specific package versions - one just has to create a local cygwin or MSys package repository, which keeps these specific versions and tell the Cygwin/MSys installer to use that one. The Cygwin installer creates a suitable repository as a cache automatically. Not sure how this works with MSys, but I guess it has similar features. The main issue here might be to get the versions mentioned in the Wiki. One might have to build them from scratch. If someone has a years old cache folder of Cygwin or MSys with all the old package versions, please put is somewhere. It would make sense to run two builds, one with the latest packages and one with an archived set of packages. Best regards, Michael .
