The problem is that path properties are interpreted relative
to the project that they are specified in.  If you propagate
them as raw strings, it probably won't work.  If you use
path-constant instead of constant, it should work.

path-constant some_headers : blah blah etc. ;

lib a : [ glob *.cc ] : <include>$(some_headers) ;
