I am trying to build caffe on Mac OS X El Captian 10.11.6 using cmake. While running `make all` command, its failing at this point.

I resolved this issue by giving runtime path to Openblas by this command.

cmake -DCMAKE_CXX_FLAGS=-I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/Headers/ ..
