CMake Error at scripts/cmake/vcpkg_download_distfile.cmake:226 (message):

      Failed to download file.
      If you use a proxy, please check your proxy setting. Possible causes are:

      1. You are actually using an HTTP proxy, but setting HTTPS_PROXY variable
         to `https://address:port`. This is not correct, because `https://` prefix
         claims the proxy is an HTTPS proxy, while your proxy (v2ray, shadowsocksr
         , etc..) is an HTTP proxy. Try setting `http://address:port` to both
         HTTP_PROXY and HTTPS_PROXY instead.

      2. You are using Fiddler. Currently a bug (https://github.com/microsoft/vcpkg/issues/17752)
         will set HTTPS_PROXY to `https://fiddler_address:port` which lead to problem 1 above.
         Workaround is open Windows 10 Settings App, and search for Proxy Configuration page,
         Change `http=address:port;https=address:port` to `address`, and fill the port number.

      3. You proxy's remote server is out of service.

      In future vcpkg releases, if you are using Windows, you no longer need to set
      HTTP(S)_PROXY environment variables. Vcpkg will simply apply Windows IE Proxy
      Settings set by your proxy software. See (https://github.com/microsoft/vcpkg-tool/pull/49)
      and (https://github.com/microsoft/vcpkg-tool/pull/77)

      Otherwise, please submit an issue at https://github.com/Microsoft/vcpkg/issues
