How to use Cmake to build and install OpenCV and Extra Modules from source and configure your Pycharm IDE

OpenCV (open source computer vision) is a very powerful library for image processing and machine learning tasks which also supports Tensorflow, Torch/Pytorch and Caffe. The library is cross platform and you can pip install it (where you are using it with Python) with CPU support. Alternatively, where for example you want to use it with GPU support, you can build it from source, which is more involved. This article is a walk through of an OpenCV build from source on a Linux Ubuntu…
