title: Using cmake with nmake x64
body: <p>I use cmake to generate a NMake file, everything goes fine.</p>
  
  <p>I use the x64 toolsets (without Visual Studio, only the SDK), so I type nmake, but it generate a x86 build and not a x64 build.</p>
  
  <p>Do you know why ? and how to force nmake to target x64 ?</p>
  
  <p>Thanks</p>
