[HELP] Compile optlink's sourcecode problems

[zhengnuo]

  I download optlink's source code, and I compile it(VS2010):

  cd os2link
  nmake

  But it always prompt: no [ntio.lib], what should I do ?

  I can't find ntio.lib, and I think tt should not be compiled 
successfully.

  So what should I do to compile optlink's source code?

  Thank you very much!


  And the optlink's FULL source code download address :
