Messages like `skipped`, `failed` and `not found`
Hi.
I got gocv and opencv installed as per the instructions given, at my Windows 11 x64 device:
D:\Development\gopath\pkg\mod\gocv.io\x\[email protected]>go run cmd\version\main.go
gocv version: 0.31.0
opencv lib version: 4.6.0
Nut during installation I got lots of messages like skipped, failed and not found some are below, is this goining to have any impact, shall I do anything then reinstall the package to get these staff fixed?
