That might explain why I have to execute do_cmake.sh again to get make executed successfully after switching the branch. However, doing what you've suggested (i.e. "rm -rf build/ CMakeCache.txt && ./do_cmake") led me to an error - https://paste.fedoraproject.org/paste/6cs1Tq3sH8XX9NrS5w-bhg. Also, running cmake after having CMakeCache.txt back (I had a backup copy), it tells me install Cython. Running "$ rm -rf build && sudo ./install-deps.sh && ./do_cmake.sh" after that did not help.
