CMake support?

[leha-bot]

Hello, it would be great if the safeclib will support build via CMake as it's more robust and cross-platform (it also adds Windows MSVC support "for free" (unless code doesn't have some C dialects)
I may try to implement it

Thanks for your attention, for your project, and sorry for interruption

Oops, I thought I already have one there. Should be trivial

Any progress on this? I can offer review support to make sure it follows modern cmake

Too busy with other stuff, but please go ahead. Also please add github actions for cmake and msvc
