I have boost, BOOST_ROOT, BOOST_BUILD_PATH variables. When i compile i receive an error:

main.cpp(2) : fatal error C1083: Cannot open include file: 'boost/shared_ptr.hpp': No such file or directory

What i do wrong?

Jamroot:
========================================================================
import boost ;

boost.use-project ;

project : build-dir bin ;

exe main : main.cpp ;
========================================================================


main.cpp:
========================================================================
#include <boost/shared_ptr.hpp>

int main()
{
  return 0;
}
========================================================================
