Subject: [Boost-build] How do I pass cxxflags to Boost libraries from within my jamfile?

(Repeating a question I posted on Stackoverflow:

I have a project with some requirements, one of which is to set the c++11
compiler/linker flags:


    : requirements
      <toolset>clang:<cxxflags>"-stdlib=libc++ -std=c++11"
      # ... etc

lib mylibrary
    : #sources
        [ glob source/*.cpp ]

The library-specific sources are being compiled with the necessary c++11 flags,
however the Boost libraries mentioned do not. This is causing no end of binary
incompatibilities and linker errors.

I do not want to specify the cxxflags explicitly in either the user-config or
the command line. I would like to make sure the jamroot/jamfiles are all that is
necessary to build the project properly.

How do I "pass in" the desired cxxflags to the dependent Boost libraries?

Also: I recently tried using an alias to accomplish my goal. From the docs:

    Another use of the alias rule is to change build properties. For example, if
    you want to use link statically to the Boost Threads library, you can write
    the following:

    alias threads : /boost/thread//boost_thread : <link>static ;

However setting this up for boost_filesystem and rebuilding, say, path.cpp still
omits the properties I am trying to build with.

What am I missing?
