Issue summary
Steps to reproduce
If you are having difficulty building Caffe or training a model, please ask the caffe-users mailing list. If you are reporting a build error that seems to be due to a bug in Caffe, please attach your build configuration (either Makefile.config or CMakeCache.txt) and the output of the make (or cmake) command.

I am trying to build this using cmake and I have installed opencv 3.1.0 in my .local directory. I have given the OpenCV_DIR in Cmakelist as follows:
set(OpenCV_INCLUDE_DIRS "/home/bramin/.local/lib/opencv/include")
set(OpenCV_LIBS "/home/bramin/.local/lib/opencv/lib/libopencv_core.so")
set(OpenCV_CONFIG_PATH "/home/bramin/.local/lib/opencv/lib/pkgconfig/opencv.pc")
---[ OpenCV
if(USE_OPENCV)
set(OpenCV_DIR "/home/bramin/.local/lib/opencv/")
include_directories(SYSTEM ${OpenCV_INCLUDE_DIRS})
list(APPEND Caffe_LINKER_LIBS ${OpenCV_LIBS})
message(STATUS "OpenCV found (${OpenCV_CONFIG_PATH})")
add_definitions(-DUSE_OPENCV)
endif()
But while doing make all I am getting following errors:
