Missing Aruco with 4.10.0 and gocv 0.37

[arkjxu]

Would appreciate some help if anyone knows whats going on, thank ya'll very much!

Simple script:

package main

import (
	"fmt"

	"gocv.io/x/gocv"
)

func main() {
	frame := gocv.IMRead("frame.png", gocv.IMReadGrayScale)
	fmt.Println(frame.Cols())
}

Running the following command:

go build -ldflags="-extldflags=-static" -o test main.go

# gocv.io/x/gocv
In file included from aruco.cpp:1:
aruco.h:12:13: error: 'aruco' in namespace 'cv' does not name a type
   12 | typedef cv::aruco::Dictionary* ArucoDictionary;

Now If I provide -tags customEnv, it would generate the following error:

go build -tags customenv -ldflags="-extldflags=-static" -o test main.go

aruco.h:5:10: fatal error: opencv2/opencv.hpp: No such file or directory
    5 | #include <opencv2/opencv.hpp>
      |          ^~~~~~~~~~~~~~~~~~~~

Setting CGO_CPPFLAGS="-I/usr/local/include/opencv4" would trigger the first error again regarding aruco errors.

FYI

I also ran the same code using the prebuilt docker image for gocv/opencv:4.9.0 and the latest gocv/opencv:4.10.0, both static and non-static versions of the image. None of them run.

Also tried to downgrade gocv to 0.36 and opencv 4.9.0, no luck, same issue.

4.8.0 and 4.8.1 works for docker. looks like anything above 4.9.0 breaks. especially the static images.

Please note that I am disabling everything except for the most basic imgproc and core and imgcodec. but looks like it's still trying to include aruco, i even tried to add the build flag for aruco.go and aruco_dictionary.go, no luck, maybe I miss something. Unless I have to include the aruco/dnn features?
