Hi everyone. I have got some problems with building openCV 4.9 for java with cuda. I did it using CMake. When i finished building in built\bin\Release\ folder i got many different dll files instead of one opencv_java490.dll or somthing like that. INSTALL (see downbelow) folder is empty. Also in configure output i see that in section java java is NO and i dont really understand that because in OpenCV modules to be build java presents it is not windows variable (JAVA_HOME) aswell . What can i do to make it work? I am new in OpenCV and dont know a lot so ask for help.
Configure output here:
