Well, you could start with :
sudo apt-add-repository ppa:antonio.chiurazzi/ppa && sudo apt-get update
sudo apt-get install pam-face-authentication
http://askubuntu.com/questions/11593...authentication
http://www.ubuntubuzz.com/2011/05/fa...cognition.html
... Then you don't have to build anything manually.


About the missing qt4 :
All library dependencies at build time are "(lib)<name>-dev" :
sudo apt-get install libqt4-dev

All prerequisites for 'pam-face-authentication'
http://code.google.com/p/pam-face-authentication/ >
> https://code.google.com/p/pam-face-a...tionFromSource
sudo apt-get install build-essential cmake qt4-qmake libqt4-dev libx11-dev libcv-dev libcvaux-dev libhighgui-dev libpam0g-dev checkinstall
