We can have multiple projects involved in a build. Consider:


Corresponding Jamfile need to be included, but before that, you'll need to
include project-root.jam for that Jamfile, which can be different from
project-root.jam from the current Jamfile. Therefore, there's a need to
search for project-root.jam during Jamfile loading.
