The usage is vcpkg, not git clone:

Direct use pad.template operator()<CodecVariant>(encoded, state, Codec::encoded_block_size() - NumSymbols);

I noticed that your latest code no longer has this macro, I hope you can release a new version

我注意到您的最新代码不再有这个宏，希望您能发布一个新版本

Yeah I'm also running into this issue when compiling with Clang on Windows, seems like the change that fixes this was already done 6 years ago so it would be nice to get a new release including this.
