This PR is a build of Bitcoin Core for Windows with Cirrus CI. It creates executable files, including bitcoin-qt.exe and packs them to NSIS installer .exe file.
It's built using MSVC toolchain with the solution files from build_msvc, so the commands in the task are different than ones used in CI folder.
Please consider this as a prototype, if making builds from single CI system could be counted as simpler approach. In such case I would make changes according to feedback and some refactoring should still be required.
