The CMake scripts will not allow dynamic linking of IPP under 32 bit Linux and output this message
On 32-bit Linux IPP can not currently be used with dynamic libs because of linker errors. Set BUILD_SHARED_LIBS=OFF
I disabled the check and everything compiles and runs perfectly.
I've done this with OpenCV 3.1 and IPP 8.2.2 and now also confirmed with OpenCV 3.3 and IPP 2018
My guess is something broke a while back and since 32 bit is in low demand, no-one has bothered to re-check?
