Well, there are several orthogonal things here:
1- the SDK you want to use
2- the minimum OS you want to support
3- the maximum OS you want to allow

You can use a newer SDK and still support older OSes.  So in your case,
you need to set MACOSX_DEPLOYMENT_TARGET to 10.3 and
MAC_OS_X_VERSION_MAX_ALLOWED to 10.3.  You can then either use the 10.3
or 10.4 SDK, either will work. (I recommend the 10.4 SDK).
 
See technote 2064:
<http://developer.apple.com/technotes/tn2002/tn2064.html>

and AvailabilityMacros.h

MAC_OS_X_VERSION_MAX_ALLOWED is a #define, so you put it in
CMAKE_CXX_FLAGS and CMAKE_C_FLAGS like so: -DMAC_OS_X_VERSION_MAX_ALLOWED=1030

MACOSX_DEPLOYMENT_TARGET is an environment variable, I'm not sure how to
set that with cmake.  Anyone? 

Also, be sure to use vtk 5, not 4.x!
