I haven't built from sources yet.

The OpenCV packages that are installed are the ones with the '[*]':

[*] libopencv-3.4.10_1         Computer vision and machine learning software library - library files
[-] libopencv-devel-3.4.10_1   Computer vision and machine learning software library - development files
[-] libopencv-python-3.4.10_1  Computer vision and machine learning software library - Python2 bindings
[*] libopencv-python3-3.4.10_1 Computer vision and machine learning software library - Python3 bindings
[*] libopencv4-4.3.0_3         Computer vision and machine learning software library, version 4.x - library files
[-] libopencv4-devel-4.3.0_3   Computer vision and machine learning software library, version 4.x - development files
[-] libopencv4-python-4.3.0_3  Computer vision and machine learning software library, version 4.x - Python2 bindings
[-] libopencv4-python3-4.3.0_3 Computer vision and machine learning software library, version 4.x - Python3 bindings
[*] opencv-3.4.10_1            Computer vision and machine learning software library
[*] opencv4-4.3.0_3            Computer vision and machine learning software library, version 4.x


After installing the opencv and opencv4 packages, there's the error:
[error] RunTime:loadLib: opencv_java (failed) probably dependent libs missing:
no opencv_java in java.library.path
[error] Save your work, correct the problem and restart the IDE!
[error] script [ recheio ] stopped with error in line 2
[error] java.lang.ExceptionInInitializerError ( java.lang.ExceptionInInitializerError )
[error] --- Traceback --- error source first
line: module ( function ) statement 
63: Sikuli (  wait )     return SCREEN.wait(target)
2: main (  <module> )     wait("1596027541334.png")
[error] --- Traceback --- end --------------

Tried to find the libopencv_java file with
find /usr/ -name libopencv_java*
but got no result.

Do you think this file can be obtained from any of the OpenCV packages
that are not yet installed (lib...) or my best bet is to install from
sources?
