Missing module functions with manually built OpenCV

[Cruaier]

Hi there,

I am currently working on a Lambda layer for object detection trying to use this module. Unfortunately I am having some issues after installing it.

My build process of OpenCV:

curl -L https://github.com/opencv/opencv/archive/refs/tags/4.10.0.tar.gz | tar zx && \ cd opencv-4.10.0 && mkdir -p build && cd build && cmake \ -DCMAKE_INSTALL_PREFIX=/opt \ -DBUILD_LIST=dnn,objdetect,imgcodecs \ -DBUILD_TESTS=OFF \ -DBUILD_PERF_TESTS=OFF \ .. && cmake --build . --target install

I am setting the needed environment variables accordingly and then install the module via npm without issues.
After installation I run some code to verify the installation:

import cv from '@u4/opencv4nodejs';
console.log(cv);
const image = cv.imread('image.jpg');

Which errors:

const image = cv.imread('image.jpg');
                 ^

TypeError: cv.imread is not a function
    at Object.<anonymous> (/var/task/test.cjs:4:18)
    at Module._compile (node:internal/modules/cjs/loader:1369:14)
    at Module._extensions..js (node:internal/modules/cjs/loader:1427:10)
    at Module.load (node:internal/modules/cjs/loader:1206:32)
    at Module._load (node:internal/modules/cjs/loader:1022:12)
    at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:135:12)
    at node:internal/main/run_main_module:28:49

Node.js v20.12.0

Logging the cv object I can see there are many functions, e.g. from dnn available...but not from imgcodecs.

Having a look into the lib64 directory of OpenCV I can see that imgcodecs lib is present.

Any leads on what is missing would be appreciated. Thanks.
