Thank you Radu!

Your answer helped and hello word is now running :)

After using --verbose I found that I do not have libcmt.lib on my 
computer at all. Though I have Visual Studio 2019 installed, it 
is for C#. Looks like when you have VS 2019, then classical 
redistributable packages are not supported any more. After a bit 
of experimenting I found adding "MSVC v142 - VS2019 C== x86/x85 
build tools (v13.20" from VS installer installed the libcmt.lib. 
After running dub with --arch=x86_mscoff from VS command line it 
worked.
