devcpp is a simple editor / ide,
that comes bundled with a (mostly outdated!) mingw compiler.
this means, no, you cannot use the prebuilt openv libs from the winpack
(they’re for msvc only)
you have to build the opencv libs from (github) src first,
using cmake, similar to what is done in linux.
(and no, we dont have tutorials for your special case)
can you report the output of g++ --version , please ?
