Petra, I am rather sceptical about MinGW, how will it survive in the competition with bash terminal offering full Ubuntu in Windows 10? This week I received a letter from a colleague from Vienna university who succeeded with installing sqltutor in the Windows bash environment.
But surely Vasileios has a point (more than a one I guess). I am planning to write down a short summary of pros and cons.

Hi everyone! 
First of all, thank you for the contributions Vasileios! You have a valid point in the fact that using one build system would be better than two. After some research, it seems that Visual Studio actually started to support MinGW - at least to some extent.  (https://devblogs.microsoft.com/cppblog/using-mingw-and-cygwin-with-visual-cpp-and-open-folder/) I plan on trying it out later this week, I will let you know what I have found out, I think it might be good to use autotools only if there were no major problems with it in VS, it would certainly make it simpler.

I should explain one of my comments further.

In auto*, the notion is that the configure code should test for a
feature, such as a library existing, or a header, or if some sample code
can be compiled.  None of this should ask "what OS am I on", so that
when it's built on a not previously contemplated OS, it just works.

cmake may have the same notion.    But almost always when I deal with
packages that have cmake build systems and that do not actually build (on
the system I am building them on), I see a lot of conditionals about OS

So I'd say that if the cmake code has "if this is a mac, do X", or
similar, that's a bug and should be removed, in favor of a feature test.

Of course, another view is that the cmake build should be only for
windows, in which case

if this os is not windows
  throw an error

is a good approach.
