1) Add overview.cpp
2) Remove overview.h from #includes
3)REGISTER_CVAR_INT (ov_radar, 1 );
  REGISTER_CVAR_FLOAT(ov_zoom , 30.0 );
  REGISTER_CVAR_INT (ov_blend, 1 );
  REGISTER_CVAR_FLOAT(ov_alpha, 1.0 );
 THAT IN CVAR.CPP
  int ov_radar; // use overview radar instead of normal radar
 float ov_zoom; // overview radar zoom
 int ov_blend; // blend mode, 0=opaque,1=mix,2=add
 float ov_alpha; // alpha 0.0 - 1.0
THIS IN Cvar.h
