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:

Please help me solve the problem.

[vsuryamurthy]

If you havent solved the problem yet, try setting OPENCV_VERSION to 3 and uncommenting USE_PKG_CONFIG in the Makefile.config followed by make all.
