after setting using zstd in project-config.jam boost.iostreams still can not detect zstd about b2

[grisumbras]

This:

[using zstd : : "/home/sr/pkgs/z/zstd/v1.5.5/1b70c2144c9d486e9526561ab9c9986e/include" "/home/sr/pkgs/z/zstd/v1.5.5/1b70c2144c9d487e9526561ab9c9986e/lib" libzstd ;]

doesn't look correct. Try this:

using zstd
   :
   : <include>"/home/sr/pkgs/z/zstd/v1.5.5/1b70c2144c9d486e9526561ab9c9986e/include" 
     <search>"/home/sr/pkgs/z/zstd/v1.5.5/1b70c2144c9d487e9526561ab9c9986e/lib"
   ;

Note: formatting is not important, I added it for clarity.

actucally I add it as
using zstd : : <include>"/home/sr/pkgs/z/zstd/v1.5.5/1b70c2144c9d486e9526561ab9c9986e/include" <search>"/home/sr/pkgs/z/zstd/v1.5.5/1b70c2144c9d486e9526561ab9c9986e/lib" <name>libzstd ;

the origin post do not display < > tags
after you post I try remove the <name> tag, and now it works
using zstd : : <include>"/home/sr/pkgs/z/zstd/v1.5.5/1b70c2144c9d486e9526561ab9c9986e/include" <search>"/home/sr/pkgs/z/zstd/v1.5.5/1b70c2144c9d486e9526561ab9c9986e/lib ;"
