[CMake] Testing for SSE and adding appropriate Compile options

[Michael Jackson]

I tried that also and it didn't work either. I am not at my windows  
box at the moment to get the exact error. I now have

if (AIMBLADE_USE_SSE)
     set_source_files_properties(${SymmetryFilter_SOURCE_DIR}/ 
FFThread.cpp
                             ${SymmetryFilter_SOURCE_DIR}/ 
FFNormalizeThread.h
                             ${AIMBlades_SOURCE_DIR}/Source/AIM/Common/ 
AIMArray_SSE.hpp
                             ${SymmetryFilter_SOURCE_DIR}/ 
LengthScaleData.cpp
                         PROPERTIES  COMPILE_FLAGS $ 
{SSE_COMPILE_FLAGS} )
endif()


  although I was trying all that on a non-clean build folder (.. I  
know.. ) so there may have been some slop still left over from other  
configuration runs..

   Is there a CMake Standard for looking for SSE and what to do? I  
tried looking through the ITK sources for "inspiration" but ITK is  
pretty complex to try and grep through the sources.
