Use the ${PROJECT_SOURCE_DIR} variable. It points to the directory
containing the CMakeLists.txt file with the last project() call.

See the ADDITIONAL_MAKE_CLEAN_FILES directory property. However, this is
going to be somewhat tricky since you are using $<TARGET_FILE_DIR:...>
in your custom command, and AFAIK the set_directory_property command is
not aware of this notation. Do you really need ball.mtk to be in the
same directory as your output file?
