我没猜错你应该在linux系统下编译window的版本，这只能用gnu的交叉编译
在linux下编译window的：

cargo build --target i686-pc-windows-gnu --release --all-features

在linux编译类linux的

 cargo build --target x86_64-unknown-linux-musl --release --all-features

openssl安装看这里

我直接在Linux下 cargo build --release就可以了，当然这不是编译windows的，不过我用你的命令编译Linux或者windows的都不行。

报错里有提示，执行下面命令后就可以了

rustup target add i686-pc-windows-gnu

没啥问题我就先关闭了
