Hello,<br>   I have downloaded the RTK vision "RTK-master.zip" in the <a href="https://github.com/SimonRit/RTK" target="_blank">https://github.com/SimonRit/RTK</a>.
 And i have installed the ITK successfully. My cmake vision is 
cmake-2.8.10.1-win32-x86. The step to build the 
ReconstructionToolkit_bin is successful. Then i click the RTK.sln and 
enter the vs2010. And i start to build the solution "F7". At last, it 
appears lots of error.<br>

........(lots of similary errors)<br>I have tried many methods to solve them,but 
failed. So i hope you can give me some suggestions. At the same time, i 
hope you can give me advice about the  detail and right steps to build 
the RTK.<br>
Best wishes.<br>Debin </div>
