Can anybody generate opencv.js?

Question

I can\'t generate OpenCV.js using this instructions: https://docs.opencv.org/master/d4/da1/tutorial_js_setup.html

I have this error:

CMake Error:

Looks like Emscripten doesn't setup the enviroment variable correctly to the SDK

For anyone trying to get this to build you need to specify the correct path to the Emscripten

which is the path where Emscripten is installed found in emsdk/upstream/emscripten

python ./platforms/js/build_js.py build_js --emscripten_dir=/home/username/Desktop/emsdk/upstream/emscripten

This should then work
