I am using Xcode 3.2.2 on Mac OS X 10.6.3.

Since these are the same as what you report, here's the link line that was causing trouble for me:

/usr/bin/c++    -Wno-deprecated -no-cpp-precomp -g -arch x86_64 -dynamiclib -headerpad_max_install_names   -compatibility_version 5.7.0 -current_version 5.7.0 -o ../bin/libvtkFiltering.5.7.0.dylib -install_name /Users/dcthomp/Build/VTK/git/bin/libvtkFiltering.5.7.dylib ... many object files ... ../bin/libvtkCommon.5.7.0.dylib ../bin/libvtksys.5.7.0.dylib -lm

and here is an example object compilation line:

/usr/bin/c++   -DvtkCommon_EXPORTS -DVTK_IN_VTK -Wno-deprecated -no-cpp-precomp -g -arch x86_64 -isysroot /Developer/SDKs/MacOSX10.6.sdk -fPIC ... lots of -I directories ... -fvisibility=hidden -fvisibility-inlines-hidden -o CMakeFiles/vtkCommon.dir/vtkDoubleArray.cxx.o -c /Users/dcthomp/Documents/Source/VTK/git/Common/vtkDoubleArray.cxx

I'm using CMake 2.8.1 and haven't changed any of the CMAKE_..._FLAGS settings.
