Subject: [PATCH] Generate Packaged/Houses dirs as dependencies

Uses add_custom_command() to add rules for generating these directories,
rather than creating them only when CMakeLists.txt runs. With this
change, you can manually delete Packaged from the build directory
without causing subsequent builds to fail.
