    Finally, note that when using Visual Studio, CMake will by default generate a 32bit executable.  
    This means the programs you compile will only be able to use 2GB of RAM.  To avoid this, you need
    to tell CMake to generate a 64bit executable.  You do this by using a command like 
-   <code_box>cmake -G "Visual Studio 10 2010 Win64" ..</code_box> instead of <code_box>cmake ..</code_box>  
+   <code_box>cmake -G "Visual Studio 10 2015 Win64" ..</code_box> instead of <code_box>cmake ..</code_box>
