I think there is some mismatch between the compiler flags you're using to<br>
build ITK and to build your application. In particular, you need to add<br>
flags for GCC to use SSE/SSE2.<br>
<br>
I'd look through ITK's CMakeCache.txt and see what flags it is setting in<br>
all the CMAKE_C_FLAGS* and CMAKE_CXX_FLAGS* CMake variables. The ITK<br>
CMake config process uses check_cxx_source_compiles to determine if the<br>
SSE intrinsics are supported. There's a stackoverflow topic on the subject<br>
