So, run nmake VERBOSE=1 to see the link/compile lines.

If you do this:
set(CMAKE_CXX_FLAGS /foo)

Then the cache value of CMAKE_CXX_FLAGS will be ignored by cmake.  It is 
usually a bad thing to do... :)

Windows is what it is.  You can not mix different run time libraries. 
There are similar things that can happen on other OSs.  It is just that 
MS provides a plethora of run time library options and none of them are 
compatible.  It means you have to be consistent with which run time you 
use in your code.   Linux and OS X have different problems, like not 
being able to run binaries built on other machines because the run time 
libraries are different.  On the threaded issue, there is still a 
-ptrhead option to gcc which can cause some trouble if you mix code 
compiled with and without it...


Anyway, none of this will help you get ITK build with VS 2010.   Where 
are you now?  Have you found the inconsistent flags in ITK and DCMTK  yet?

You want to look in the build tree of both and check out the flags.make 
and the build.make files:
CMakeFiles/target.dir/flags.make   // this will have the compile flags
CMakeFiles/target.dir/build.make   // this will have the link flags

I think the link flag is what you want, something like:   /MDd
