For VS 8, in Cmake and VTK, we do this:

IF(CMAKE_COMPILER_2005)
  ADD_DEFINITIONS(-D_CRT_SECURE_NO_DEPRECATE -D_CRT_NONSTDC_NO_DEPRECATE)
ENDIF(CMAKE_COMPILER_2005)

Also, if you are adventurous and like the command line....

You can use cmake to create makefiles for "Unix Makefiles", but set CXX 
and CC to cl.
Make sure cl command line environment is setup correctly.  Then you can 
use make -j3  to do
the build.   Due to a bug in the cygwin make, you have to use this 
patched one:
http://www.cmake.org/files/make.exe

This will only work with Vs 2005 because before that the compiler could 
not run more than
one file at the same time.   (it wrote to a .pdb file that was shared 
between object files at the
same time.)   The VS 2005 ide will do stuff in parallel, but not as much 
as gmake.
