Attached a patch which prevents this. It's still several times faster.
For each cpp file a file is created where the compiling could be
suppressed with a macro, for instance:

// autogenerated file
// clear it to build it again by cmake
// look for non-const files
#define DONT_INCLUDE_CONST_FILES
#include "C:/sandbox/kde/b/kdecore/_all_kdecore_final_cpp.cpp"

#ifndef kconfigbackend___ASSUME_CONST
#include "C:/sandbox/kde/kdelibs/kdecore/config/kconfigbackend.cpp"
#endif
