I get the following error when building cool-retro-term using gcc version 10.3.0:

lib/TerminalCharacterDecoder.cpp: In member function ‘virtual void Konsole::HTMLDecoder::decodeLine(const Konsole::Character*, int, Konsole::LineProperty)’:
lib/TerminalCharacterDecoder.cpp:205:18: error: ‘iswspace’ is not a member of ‘std’; did you mean ‘isspace’?
  205 |         if (std::iswspace(ch))
      |                  ^~~~~~~~
      |                  isspace
make[1]: *** [Makefile:800: TerminalCharacterDecoder.o] Error 1

It builds fine without modification using gcc@9.4.0. With the following patch I'm able to build successfully using gcc 10.3.0:
