how to overcome building error when I'm using bcp to export boost thread?

Question

I'm using boost bcp tool to export thread library from boost. The layout of exported library is

- Jamroot
+ libs
  |----- + thread
           |----- + build
                    |----- - Jamfile.v2
+ boost
+ doc

Now when I run bjam in build library is getting me :

boostcpp.jam: No such file or directory
../../../Jamroot:138: in modules.load
rule boostcpp.set-version unknown in module Jamfile</Users/miladrezayee/Softwares/developer/boost_1_53_0/tmp1>

/Users/miladrezayee/Softwares/developer/boost_1_53_0/tools/build/v2/build-system.jam:570: in load

I exported system libray and when I run *bjam in build folder, it compiles successfully. I don't why thread library can't compile? Anybody have any idea what is going wrong with thread library?

Ok, I found the solution you should bcp like the following

$ bcp build /path/of/exported/thread 
$ bcp chrono /path/of/exported/thread

Now I can run bjam on root path of exported thread library and it's compiling successfully.
