This sounds good.  Switching to cmake has been on the to-do list for a while
and if your cmake configs look good it will become the official build system
soon.

For windows support w/o VC++, perhaps you can look into MSYS2? 

MSYS2 has [and you'll like this] the Arch package system; once you have a 
core MSYS2 installed, you can pacman -S <pkg> and pacman -Syu to update the 
whole enchilada.  Besides, MSYS2 also has a alternative C-runtime libraries.

Both GCC and clang are available, even ARM target support is in there..

For other projects, I've been using cmake for a bit, and VC++ CE 2019
which I'm using has cmake-generator to flesh out VC++ project files;
this is a huge part of my motivation to switch to CMAKE as updating
the stupid proect files "by hand" is going to be a thing of the past.
