I disagree. From the docs:

add_subdirectory: Add a subdirectory to the build.

  add_subdirectory(source_dir [binary_dir] 
                   [EXCLUDE_FROM_ALL])


The second argument is the binary_dir, which he is setting to be the
same as his source_dir. Hence, an in-source build of mylib and myapp.
