Example/CMakeLists:
- Converted to Qt5, because 4 was not compatible with Mavericks (a define in Qt told me) and my dependencies where such, that porting required minor modification to my source.

Example/main.cpp:
- Specifying a subfolder for headers seems to be wrong now (#include <QtGui/QApplication> -> #include <QApplication>).

Src/CMakeLists.txt:
- Converted to Qt5.

UnitTests/CMakeLists:
- Converted to Qt5.
- Added compile definition “-DGTEST_USE_OWN_TR1_TUPLE=1”, because this seems to be not available on some plattforms (e.g. Mavericks).
- Adding compile flags using “set_target_properties” fails, if the “GTEST_CXX_FLAGS” variable is empty (i.e. there were now special flags to pass). The variable is now tested against the empty string before adding it to the compile flags.
