Summary0012377: CMake misparses -g0 as enable debug
DescriptioncmGlobalXCodeGenerator.cpp missparses -g0 (disable debug) as ENABLE, see following code:

  std::string gflagc = this->ExtractFlag("-g", cflags);
  // put back gdwarf-2 if used since there is no way
  // to represent it in the gui, but we still want debug yes
  if(gflagc == "-gdwarf-2")
    {
    cflags += " ";
    cflags += gflagc;
    }
  std::string gflag = this->ExtractFlag("-g", flags);
  if(gflag == "-gdwarf-2")
    {
    flags += " ";
    flags += gflag;
    }
  const char* debugStr = "YES";
  if(gflagc.size() ==0 && gflag.size() == 0)
    {
    debugStr = "NO";
    }
Steps To ReproduceSet -g0 in CXX or C flags.

The gcc man page indeed says:

"-glevel Request debugging information and also use level to specify how much information. The default level is 2.
Level 0 produces no debug information at all. Thus, -g0 negates -g."

Implementing this is a bit trickier then just changing the flag, as we need to honor ordering.
Attached patch fixes the issue.
