Hello, i have written a small program which evaluates a model (res10_300x300_ssd_iter_140000_fp16.caffemodel). This is working fine. I want to compare opencl with cpu only model

I set setPreferableTarget(DNN_TARGET_CPU); to force cpu usage.

In Logs

[ INFO:0] Initialize OpenCL runtime...

The measured time still the same(42ms). Well to make very sure - i decided to recompile without open cl

cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local -DWITH_OPENCL=OFF -DBUILD_DOCS=ON -DBUILD_EXAMPLES=ON ../opencv-3.4.1-src

and after that

 make -j7

In Logs

[ INFO:0] Initialize OpenCL runtime...

Still - the measured time still the same(42ms) and i got the open cl log. Did i failed to reinstall successfully or does open cv always uses open cl? Very confused.
