As Cristian surmised we use msys2/mingw64; we download from
www.msys2.org (the x86_64 option).  Then install the mingw64 toolchain,
and use mingw64 shells:

pacman -Sy msys2-devel
pacman -Sy mingw-w64-x86_64-toolchain
pacman -Sy base-devel
pacman -Sy mingw-w64-x86_64-check
pacman -Sy mingw-w64-x86_64-qt5
pacman -Sy mingw-w64-x86_64-qwt-qt5
pacman -Sy mingw-w64-x86_64-doxygen
pacman -Sy mingw-w64-x86_64-boost
pacman -Sy mingw-w64-x86_64-git-lfs
pacman -Sy mingw-w64-x86_64-gsl
pacman -Sy mingw-w64-x86_64-netcdf
pacman -Sy mingw-w64-x86_64-curl
pacman -Sy mingw-w64-x86_64-postgresql
pacman -Sy nano scons vim git procps

cmake was installed via:

pacman -Sy cmake
