Pam Face Authentication Musings : Autotools and Qt Gui Project

Qt projects are usually packaged using a nice utility called qmake.But i am more comfortable with the autotools way. So after some intensive google searching. I finally figure out how to add the UIC (User Interface (.ui) to C Code) and MOC (Meta Object Compiler - which handles the signals and slots)

Configure.ac

  

#                                               -*- Autoconf -*-

# Process this file with autoconf to produce a configure script.
