Linker options: Where are they? [message #1835343]

I linked OpenCV via Maven into my Java project.(I'm working with Eclipse IDE for Java Developers, Version 2019-09 R (4.13.0)). When loading the OpenCV lib I get a warning from the VM about the stack of the OpenCV lib and a recommendation:
"It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'."
Now I would like to link OpenCV with '-z noexecstack' but I don't know where to put this.

Does anybody know?

Uwe

P.S.: OpenCV is running smoothly, I just want to get rid of the warning.

If both static and shared libraries are found, the linker gives preference to linking with the shared library unless the -static option is used. It makes a difference where in the command you write this option; the linker searches and processes libraries and object files in the order they are specified.
