FindOpenCVPkg
|
|
-----------
|
|
|
|
Searching OpenCV components on systems which does not have fully installed OpenCV.
|
|
Such systems does not include OpenCVConfig.cmake and OpenCVConfigVersion.cmake files.
|
|
Example of such system is Ubuntu 18.04.
|
|
This package try to use OpenCV config file first if it exists.
