I think the use of GNU make VPATH is fairly common.  For example, I
believe the autotools build a tree that matches the srcdir structure and
add Makefiles that contain something like this:

  VPATH = ../../wherever/notmuch/thisdir
  ...

Of course, given that, the build tree doesn't include any source files.

FWIW
