Recover opencv2/ opencv4 folders from /usr/include

I had a lot of problems with my opencv installation and along the way I accidentally deleted the opencv folders in /usr/include. How can I recover them in the right way so that the following error doesn't occur when I try to catkin_make my ros workspaces?

Would it be possible to copy the folders from /usr/local/include to /usr/include since I have those left from the successful installation or will that lead to problems?

Solution 1:

You have to simply use the power of APT to restore /usr/include folder contents:

sudo apt-get install --reinstall \
$(dpkg -S /usr/include/ | sed "s/,//g" | sed "s|: /usr/include||")

The /usr/local/include folder is not controlled by APT, so its restore is not possible by using above command.
