Boost iostreams with zstd support on Windows

[jrade]

How do I build Boost on Windows with iostreams with zstd support?
I have tried lots of things including

b2 -sZSTD_INCLUDE="C:\Libraries\zstd-v1.5.2-win64\include" -sZSTD_LIBPATH="C:\Libraries\zstd-v1.5.2-win64\dll" -sZSTD_BINARY="libzstd"

Thank you

If zstd is not findable generally in compiler and/or in the OS you'll need to declare it in one of the B2 config files (https://www.bfgroup.xyz/b2/manual/release/index.html#bbv2.overview.configuration) as:

using zstd : : <include-path>"C:/Libraries/zstd-v1.5.2-win64/include" <search>"C:/Libraries/zstd-v1.5.2-win64/dll" <library-name>libzstd ;
