I have gone through the readme file from HERE
I have installed cmake and downloaded the the sourcecodes for both opencv and opencv_contrib repository.(Placed them both in the same folder)
Cmake is identified as 'Command not found' and im unable to proceed further
Heres the command I used from the build folder I created in the opencv folder
cmake -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-3.4.1/modules/
I tried using the GUI as well to include the dpm module but run into this error:
It would be really helpful if anyone could post the step by step approach here as there seems to be no place with the one stop solution for this.
