Brief problem description

I place using zstd in project-config.jam try to build boost.iostreams with zstd enable.
but it does not detect zstd
here is the using.
[using zstd : : "/home/sr/pkgs/z/zstd/v1.5.5/1b70c2144c9d486e9526561ab9c9986e/include" "/home/sr/pkgs/z/zstd/v1.5.5/1b70c2144c9d487e9526561ab9c9986e/lib" libzstd ;]

Steps to reproduce the issue

tar xf boost_1_84_0.tar.bz2
cd boost_1_84_0
./bootstrap.sh
add
using zstd : : "/home/sr/pkgs/z/zstd/v1.5.5/1b70c2144c9d486e9526561ab9c9986e/include" "/home/sr/pkgs/z/zstd/v1.5.5/1b70c2144c9d486e9526561ab9c9986e/lib" libzstd ;
to the project-config.jam
run ./b2 --reconfigure

Actual behavior summary

it dected zstd as

• zstd : no

Expected behavior summary

I think it should detect zstd right.

[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.

[xiongyang]

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 ;"
