ENH: when trying to find a FooConfig.cmake file, if in the directory pointed

to by the Foo_DIR variable there is no FooConfig.cmake file, then instead of
abort and complain that the user should set or clear the Foo_DIR variables,
just search for the file and discard the old Foo_DIR contents

The tests succeed, ok by Brad.
