当出现No rule to make target ，肯定是Makefile有问题。
有的makefile是脚本生成的，你得看脚本的配置文件对不对。
我的是这个脚本生成的。发现是Pythondir的配置不对：
PYTHON_DIR=/home/zgq/anaconda3
cmake
-DPYTHON_LIBRARY=$PYTHON_DIR/lib/libpython3.5m.so
-DPYTHON_INCLUDE_DIR=$PYTHON_DIR/include/python3.5m
-DPYTHON_INCLUDE_DIR2=$PYTHON_DIR/include
-DBoost_INCLUDE_DIR=/usr/local/include
-DBoost_NumPy_INCLUDE_DIR=/usr/local/include
-DBoost_NumPy_LIBRARY_DIR=/usr/local/lib
-DOpenCV_DIR=/usr/local/share/OpenCV
-Wno-dev
. && make
改过来就OK了
