This commit makes use of the "slicer/slicer-base" docker image based
of "slicer/buildenv-qt5-centos7". See .
Thanks to the ability of CircleCI to directly run program within
a selected image, there is no need to use the "slicer/slicer-dependencies"
image. We can directly call the "BuildSlicer.sh" script.
Note that execution of test is currently disable.
