CUDA compilation issue with CMake

[yaochx]

follow the tutorial
mkdir build
cd build
cmake ..
make
I got the errors I get are as follows:
`/usr/lib/gcc/x86_64-linux-gnu/4.8/include/stddef.h(432): error: identifier "nullptr" is undefined

/usr/lib/gcc/x86_64-linux-gnu/4.8/include/stddef.h(432): error: expected
a ";"

/usr/include/x86_64-linux-gnu/c++/4.8/bits/c++config.h(190): error:
expected a ";"

/usr/include/c++/4.8/exception(63): error: expected a ";"

/usr/include/c++/4.8/exception(68): error: expected a ";"`

This worked for me using CUDA 7.0.74, gcc/g++ 4.8.4 and CMake 2.8.12.2

The C++11 flag should be turned on in CUDA code compilation

With CUDA 7 and JetPack 2.2 / L4T R24.1, this is the branch of the repo to use: https://github.com/dusty-nv/jetson-inference/tree/L4T-R24.1

With updates to CUDA 8, JetPack 2.3 / L4T R24.2, and Ubuntu 16.04 (which is on master branch), I had to remove the nvcc c++11 flag because it started complaining about seeing the flag twice (as is also included in CXX flags for normal non-CUDA compilation).
