  --NOTE: this autocmd was written only to handle very rare case when inside directory
  --without CMakeLists.txt neovim starts like `nvim CMakeLists.txt`. In this case initial
  --setup will not make the affect and to correctry process the file save, we need to create
  --this autocommand so it reinitializes the project if it has not been done before. IMHO this
  --is not the best way to do this. Also, if newly buffer associated with CMakeLists.txt will not
  --be saved and just closed, but user will continue to use nvim, CMake commands still will be
  --able while it sholdn't. Two options is give up or handle all this corner cases
