+\r
+I think the use of GNU make VPATH is fairly common.  For example, I\r
+believe the autotools build a tree that matches the srcdir structure and\r
+add Makefiles that contain something like this:\r
+\r
+  VPATH = ../../wherever/notmuch/thisdir\r
+  ...\r
+\r
+Of course, given that, the build tree doesn't include any source files.\r
