But can this be done when the examples and tests directories are subdirectories of the library
directories?  Can the build proceed in this order?

vtol
vdgl
vtol/tests
vtol/examples
vdgl/tests
vdgl/examples

I don't see how to do this other than by building once without building examples and tests and then
by building again with them.

I'm afraid I'm not really sure whether this worked with 1.2.  I don't know if this problem was
introduced by 1.4 or by some changes in the VXL tree.
