The pro2cmake.py file is now smarter, and can reapply "special case"
modifications after regenerating a CMakeLists.txt file.
This substantially lowers the maintenance burden when regenerating
many files at once.
See the special_case_helper.py file for details on how it works.
Make sure to commit the generated .prev_CMakeLists.txt file alongside
your CMakeLists.txt changes.
To disable the preservation behavior, you can pass -s or
--skip-special-case-preservation to the script.
To keep around temporary files that are created during this process,
you can pass -k or --keep-temporary-files.
To get more debug output, pass --debug-special-case-preservation.
