I would be thankful for a Visual Studio project (or a project of any other IDE), or instructions to compile, if any

Best I can do is give you this link to the old guide on the ancient forums.
If that doesn't help, try PM'img Lampshade or wait for one of the more programmy people to show up and post.

Welcome Kuzma!
I used 4zb4's link with great success, I'm glad to see the old forums still survives to leak its holy knowledge to us. I ended up modifying the makefile which seemed to be the most straightforward way. mingw is good and compiled the LIVAN source for me and I recommend it (I felt quite manly when it compiled for the first time). I used Programmer's Notepad 2 to make a short-cut that automates the build command (but that's a pretty standard thing to do when you're not a command-line junkie).

While I don't use Visual Studio for code compilation (for some strange reason), I definitely use it for source-diving since it has a totally indispensable search-tool. If you can get LIVAN to compile via VS, then stick with that because then you'll be able to do everything from one package.
