Kornel Benko 2ec243d47b Cmake build: Fine tuning 
1.) If building with external iconv, remove remnants of libiconv data
  created if previousy used internal iconv
2.) Remove the variable HELP from cache to enable subsequent builds.
  (Different variable-handling on new cmake (version >= 3.18))
3.) New macro to extract cmake-known-cxx-sts features
4.) Check for CXX11-features only for a subset of possibilities
  known by the used cmake
