Are you sure that
is right? All bjam targets created by Boost.Build have some grist.
For reference, here's how virtual-target.jam creates 'alias' targets
can are used to request specific file on the command line:
# For a real file target, we create a fake target depending on the
# real target. This allows us to run
# bjam hello.o
# without trying to guess the name of the real target. Note that the
# target has no directory name and uses a special <e> grist.
# First, that means that "bjam hello.o" will build all known hello.o
# targets. Second, the <e> grist makes sure this target won't be
# confused with other targets, for example, if we have subdir 'test'
# with target 'test' in it that includes a 'test.o' file, then the
# target for directory will be just 'test' the target for test.o
# will be <ptest/bin/gcc/debug>test.o and the target we create below
# will be <e>test.o
DEPENDS $(target:G=e) : $(target) ;
# Allow bjam <path-to-file>/<file> to work. This won't catch all
# possible ways to refer to the path (relative/absolute, extra ".",
# various "..", but should help in obvious cases.
DEPENDS $(target:G=e:R=$(path)) : $(target) ;
So, for this to work you need to add INCLUDE on the same targets that are created
