C++ 11 is necessary to compile with latest image_geometry package

[alexzzhu]

The image_geometry package now compiles with C++ 11 by default: (https://github.com/ros-perception/vision_opencv/blob/8b5bbcbc1ce65734dc600695487909e0c67c1033/image_geometry/CMakeLists.txt#L15) , and uses std::shared_ptr: (https://github.com/ros-perception/vision_opencv/blob/8b5bbcbc1ce65734dc600695487909e0c67c1033/image_geometry/include/image_geometry/pinhole_camera_model.h#L273).

At present, image_pipeline does not compile with C++ 11, which causes the compiler to crash when compiling with image_geometry.

I believe I'm having the same issue. The build fails with:

[ 52%] Building CXX object image_pipeline/image_proc/CMakeFiles/image_proc.dir/src/nodelets/rectify.cpp.o

std::shared_ptr cache_; // Holds cached data for internal use

This is resolved by specifying c++ 11 in the CMakeLists:
SET(CMAKE_CXX_FLAGS -std=c++11)

If having c++ 11 is an acceptable assumption moving forwards, I can make a PR to put this into the main branch.

Yes, please do

Sorry for the delay, 98670bd fixes it properly.
