问题遇到的现象和发生背景
我想用vcpkg安装gmp这个包，然后直接vcpkg install gmp的话，老是失败。
然后我就想采用知乎上搜到的方案，直接去手动下载，然后将压缩包复制到vcpkg/downloads中去，
再执行vcpkg install gmp，最后发现还是不行
问题相关代码，请勿粘贴截图
（1）先用vcpkg install gmp找到下载地址：
PS C:\src\vcpkg> vcpkg install gmp

（2）找到github下载地址如下：
https://github.com/ShiftMediaProject/VSYASM/archive/deb50d9f18e8461538468339d508cdf240e64897.tar.gz
（3）下载好后就把压缩包复制到了vcpkg/downloads目录下。
（4）再次执行vcpkg install gmp，发现还是失败。
运行结果及报错内容
（5）报错内容如下，与复制前一样的报错内容，下面是接着后面的

Failed to download file with error: 1
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
