I'm using boost BJam to build my project with externals librairies.
And I need to define variables if I found headers on the machine.
How can we do that ?
project
    : requirements
    <include>.
    <define>FLAG_NEEDED_TO_DEFINE     => I need to define only if I found
header.
    ;
lib library : [ glob *.cpp ] ;
At the moment the easiest way to do this is:

// header.cpp
#include 

# Jamfile

import configure ;

obj header_test : header.cpp ;

project
  : requirements
    [ configure.check-target-builds header_test
      "header.h exists" : <define>FLAG_NEEDED_TO_DEFINE ] ;
