Building kak-lsp for Cygwin/Msys2

Ya, I’m using WSL now too, since my work computer just got upgraded from Win7 to Win10. Before, I had sorta given up on trying to get it to work on Cygwin.

And I’ve been promised to soon get a RHEL installation to dual boot with, and then I’ll finally be (mostly) free from Windows BS™ :smile:
