Problem building on c++-4.9 or ubuntu 16

Hey,

Thanks for the port to recent CUDA. I got an issue when compiling on a recent C++-4.9 or ubuntu 16.04 (I think it is related to C++):

$ cmake ..
$ cmake ..

Hi,

It is related to your CUDA toolkit 7.5. You should add the following line to CMakeLists.txt at line 14:

SET (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wno-format-security -D_FORCE_INLINES")
