The packages listed on the Wiki page draw in a bunch of dependencies afaik. Reinstalling only those doesn't reinstall all their dependencies.
I'd try to reinstall the packages that contain the libraries that cannot be found.
So start with
sudo apt-get --reinstall install libqt5network5

and check if that makes the first error disappear.

Than proceed with the other ones until the build is clear.

HTH,
