CMake Port/Porting Guide

• Process of getting new CMakeLists.txt files, ideally:
  • Run the conversion script pro2cmake.py
  • Edit the places which fail by hand, add a comment "# special case" next to the manual changes, this helps with future git diffs when re-running the script.
  • When the conversion script was fixed, and it is re-run:
    • Either the code next to the comment is fixed automatically
    • Or the hand-edited version needs to be kept
