Increase minimum CMake version to allow builds on Focal Fossa (Noetic)

[gavanderhoorn]

See ros/catkin#1052.

I created a bash script to automate this, it is quite simple:

#/bin/bash
mkdir /tmp/ros-i
cd /tmp/ros-i
git clone git@github.com:ros-industrial/motoman
git clone git@github.com:ros-industrial/kuka_experimental

cd /tmp/ros-i
for DIR in `ls`;
do
    if [ -d $DIR/.git ];
    then
            echo "...Checking changes for $DIR"
            cd $DIR
            git checkout -b CMakeVersionFocal
            git commit -am 'Increase minimum CMake version to allow builds on Focal Fossa (Noetic)'
            git push git@github.com:ipa-nhg/$DIR CMakeVersionFocal
            cd ..
    fi
done

I will open the derived PRs but probably it will not make sense for many of the repos, likely because they contain an old distro version. For those repos without a CI system for focal I will set the PR as draft and ask the maintainer to decided if the PR should be closed or can be set as "ready" and merged.
