How do I setup openCV

[Guille]

Im having problems setting it up in codeblocks, it doesnt detect cv::, I've linked and set the build options but dunno if thats correct.

What do you mean by "doesn't detect"?

Depending on the os, on linux it is often enough to add e.g.

Code Select Expand

`pkg-config opencv4  --cflags` under Project options | other compiler options and

Code Select Expand

`pkg-config opencv4 --libs` under other linker options. Then the compiler can find the includes and the linker the libraries.

Code completion might be a different story. I do not care a lot about it.
