Converting a cpp file with opencv modules to wasm

Could someone please help me with converting a cpp file that includes opencv modules to wasm? what are the steps I need to achieve the same? I tried the documentation Building Projects — Emscripten 2.0.16 documentation . But I have encountered several errors when I ran the emcmake cmake command on the opencv source. Could someone point me in the right direction?
please check this link for details regarding my issue here
I’m actually not sure if these are even the right steps to take in order to compile my application to wasm.

Basically I want to run my simple cpp application that prints a matrix and uses opencv module in the browser using wasm through emscripten.

Please help.

There seems to be a problem with ittnotify. It should be possible to leave it off an OpenCV build by turning Cmake flags BUILD_ITT and WITH_ITT off. If I understand right, it is optional and for just profiling purposes.

yes! you are correct. Thank you.

now I get this error…

Users/atul109/MyDocuments/work/new/emscripten_playground/opencv-3.4.14/modules/core/include/opencv2/core/hal/intrin_wasm.hpp:1566:1: error: always_inline function ‘wasm_v128_load’ requires target feature ‘simd128’, but would be inlined into function ‘v_load’ that is compiled without support for 'simd128’


Please help.
