With view-pathing off, the following example obtains all the quoted include files from
dir1 only if they are not found in the directory of a.C and from dir2 only if they are
not found in dir1. Finally, if necessary, the standard include directories are searched.
Angle-bracketed include files are searched for in dir1, then dir2, followed by the
standard include directories.
aCC -Idir1 -Idir2 -c a.C
With view-pathing on, the following example searches for quoted include files in dir1

include directories.
