How to integrate generated opencv with extra modules into an IntelliJ Java project in Windows 10

Question

I successfully generated opencv with extra modules from opencv_contrib in version 4.6.0. As a result, amongst others, I got the library opencv_java460.dll, opencv_core460.dll and opencv_460.jar. I installed the jar manually using maven in my local repository and referenced it in my Java project's pom.xml. Once using the library in my code, I got UnsatisfiedLinkError when e.g. using Mat.eye() even after calling System.load(path/to/opencv_core460.dll) beforehand.

Can somebody please explain how to integrate the generated sources correctly within a Java project in IntelliJ on Windows 10?

Answer 1

I solved the issue by applying the flag BUILD_FAT_JAVA_LIB in CMAKE-GUI and now it works flawlessly.
