I'm using Boost through the Jamfiles directly (that is "use-project
boost : [ os.environ BOOST_ROOT ] ;"). When creating some libraries I
introduce features for its build variants:
feature usewide : no yes : propagated ;
lib foo : foo.cpp
Now users of this lib and boost, like:
exe bar : foo /boost//system ;
they will force the feature "usewide" on boost as well. Boost will have
"usewide-no" in its build path, but boost will not be affected by the
<define> anyhow. Is there a way not to propagate the feature to boost?
With several libraries the features will make the path be too long and
additionally boost will be recompiled for each feature, needlessly.
I could imagine some "realm" for features, marking all targets where the
feature must affect the build path. And a way to propagate only
"upwards", meaning from the lib up to the exe, but not from the exe down
Could that be useful to others?
