- Now works on Mac OS X 10.9 (Mavericks)

CMakeLists.txt:
- Added add_definitions( -DGTEST_USE_OWN_TR1_TUPLE=1 ) as to suppress an error if the corresponding tuple headers are not found on a system (e.g. Mac OS X 10.9)
CMakeLists.txt:
- Compiles under Mac OS X Mavericks and Ubuntu 12.04.
- Must have accidentally deleted a function call to setup up linker and
  compiler flags. Added the line again.
