[cmake-developers] Configure File and #cmakedefine

[Andy Cedilnik]

Hello,

There is a code in cmMakefile.cxx:

      if(!cmSystemTools::IsOff(def))
        {
        cmSystemTools::ReplaceString(line, "#cmakedefine", "#define");
        output += line;
        }
      else
        {
        cmSystemTools::ReplaceString(line, "#cmakedefine", "#undef");
        output += "/* ";
        output += line;
        output += " */";
        }

This code handles the following cases:

#cmakedefine
  #cmakedefine

but not:

# cmakedefine

Unfortunately to properly handle the last one, we would need to
replace with regular expression or some manual parsing. This would
slow down the configure file.

Maybe we could check if the line contains cmakedefine and then parse.

Comments?
