To use 9externally you would need a `use-project` declaration and to use the 10project as a dependency where needed: 11 12---- 13use-project /hash-predef : /path/to/hash-predef/root ; 14 15exe my_thing : main.cpp : <dependency>/hash-predef ; 16---- 17 18To use in your project tree you would only need to place the Predef tree 19in a subdirectory and reference the project location as a dependency where 20needed. 21 22---- 23exe my_thin : main.cpp : <dependency>libs/hash-predef ; 24---- 25|# 26 27import project ; 28 29path-constant BOOST_PREDEF_ROOT : . ; 30path-constant BOOST_PREDEF_INCLUDE : include ; 31constant PREDEF_DIST : boost ; 32 33project /boost/predef 34 : usage-requirements 35 <include>$(BOOST_PREDEF_INCLUDE) ; 36 37if [ project.is-jamroot-module $(__name__) ] 38{ 39 local attributes = [ project.attributes $(__name__) ] ; 40 $(attributes).set "build-dir" : .bin ; 41} 42 43alias libs ; 44
