Hi Ashish,

Handling the new crt dlls can be very tricky... I circumvent them by 
statically compiling them into my projects.

In cmake, everywhere you see "/MD" or "/MDd" change it to "/MT" or "/MTd".

Within Visual C++, go to the project properties page, click 
"Configuration Properties", then "C/C++", then "Code Generation". In the 
table on the right pane, change the "Runtime Library" to "Multi-threaded 
(/MT)" or "Multi-threaded (/MTd)" if your building a debug version.

You wont have to worry if other windows machines have the new 
MSVCP80.dll etc. files when distributing your app.
