discover-tests
--------------

* The :command:`discover_tests` command was added to support registering tests
  discovered at test time by :manual:`ctest(1)`. It runs a user-provided
  discovery command, parses its output, and generates test names, arguments,
  and properties from regular-expression captures.

* Test drivers generated by the :command:`create_test_sourcelist` command now
  support the `-N` option to list all tests, one per line.  This is useful in
  combination with the new :command:`discover_tests` command.
