[Scons-users] Scons does not knkow how to Make File Target after adding Variant Build

[Malek Musleh]

I think I might have found the problem: There are a bunch of
side-projects in the same build directory whose SConscript files need
to have variant_dir added.

Is there a way to print out the list of SConscript files read just
before scons starts building?
