// How to build Intel-Caffe with MKLDNN backend
// ============================================
// mkdir build && cd build
// cmake -DCMAKE_BUILD_TYPE=Release \
//       -DUSE_MKLDNN_AS_DEFAULT_ENGINE=ON \
//       -DUSE_MKL2017_AS_DEFAULT_ENGINE=OFF \
//       -DCPU_ONLY=ON \
//       -DCMAKE_INSTALL_PREFIX=/usr/local .. && make -j8
// sudo make install
//
// In case of problems with cublas_v2.h at include/caffe/util/device_alternate.hpp: add line
// #define CPU_ONLY
// before the first line
// #ifdef CPU_ONLY  // CPU-only Caffe.
