NMake Makefiles: Support Visual Studio 2019 better

fanc999-1 · kjellahl · commit 9941045fca57 · 2020-06-18T11:07:13.000+02:00
Make Visual Studio 2019 builds distinct from 2017 builds.  Note that for the
libsigc++-2-10 branch, we do not distinguish between Visual Studio 2015, 2017
and 2019 in regards to the built DLL and .lib filenames, since they are
found to be interchangeable.
