I did oversimplify and mixed things.

ADD_TEST macro does only specify what command is to be run for the named test
then the ctest command (directly called or through make test) runs the
specified executables.

the ctest command itself may do far more operations (CVS/SVN checkout/update,
configure/build with CMake, run the tests exe, publish to  dashboard etc....)

thus the example in the CMake book.
I don't have a copy of this book so I may not check but I would guess
that the enclosing project where you find the add_test with ctest call example
is not the same project as the one that will be generated whithin add_test,
so you do not have the recursion project but just a project A test which role
is to build and run a project B test.

Just a guess, because without the book :-)
