sudo apt-get install qt5-default qt5-qmake qtbase5-dev-tools qtcreator  libglu1-mesa-dev mesa-common-dev

Then from the FreeCad ppa (make sure you have http://ppa.launchpad.net/freecad-maintainers/freecad-daily/ubuntu in your apt sources list):
sudo apt-get install oce-draw liboce-modeling-dev liboce-ocaf-dev

1. Demonstrate the operations for the OpenCASCADE viewer, such as pan, zoom and rotate;
   the view manipulate mainly by the middle button of the mouse, and left button is used
   to pick and select;
2. Demonstrate the primitive shape construction algorithms usage, such as box, cone,
