I built [opencv][1] with the following cmake options:

    cmake  -G "Eclipse CDT4 - Unix Makefiles" -D CMAKE_BUILD_TYPE=RelWithDebInfo -DWITH_TBB=OFF -DWITH_OPENMP=ON -DCMAKE_C_COMPILER=icc -DCMAKE_CXX_COMPILER=icpc -DCMAKE_CXX_FLAGS="-debug inline-debug-info -parallel-source-info=2 -ipo -parallel -xCORE-AVX2 -Bdynamic" ..

However, when I try to build (with `icpc`) the application which uses opencv (built with `icpc`) these warning messages appears:

    icpc -shared-intel -L/home/luca/ParallelOpenCV/originalOpenCV/lib -parallel -o "SURFAllInOne"  ./main.o ./surf.o   -lopencv_core -lopencv_xfeatures2d -lopencv_highgui -lopencv_imgproc -lopencv_imgcodecs

What does this means? The code is correct but I wonder if I should bother about this (especially if this make the code slower, I talk about it [here][2])
