Support for native Windows

[EricEngle-NOAA]

Are we planning to fully support the Windows platform? By that I mean native Windows and the MS Visual Studio C/C++ compiler toolchain, not MSYS2-based builds.

A little context...I have spent a good amount of time today trying to get successful windows build for NCEPLIBS-g2c for the g2clib conda forge feedstock. I had some success introducing some patches, but ultimately there is too much added code in v2.0.0+ that breaks on non-POSIX platforms. So we have decided to stop building for Windows for v2.0 and v2.1.

Which brings up the original question...about if we want to truly support Windows? I have several patches that can be turned into commits for better supporting Windows in a future release.

@Hang-Lei-NOAA - I am formally starting work to build g2c on Windows natively using the MSVC compiler toolchain and using the vcpkg package management system to install the dependent libraries.

@EricEngle-NOAA thanks for your work. You can create a branch to share. But we don’t have plans to support libraries on windows. Let Alex know this work @AlexanderRichert-NOAA
