- Compiles under Mac OS X Mavericks and Ubuntu 12.04.
- Moved to Qt5 as Qt4 does not support Mavericks.
- The way to use Qt with cmake depends on the version of cmake. Since we
  like to support Ubuntu 12.04, we need to choose the way supported by
  cmake 2.8.7. See the nice documentation at
    http://qt-project.org/doc/qt-5/cmake-manual.html
  on how this is done.
- Changed to the macros supported by cmake 2.8.7
