當出現No rule to make target ，肯定是Makefile有問題。
有的makefile是腳本生成的，你得看腳本的配置文件對不對。
我的是這個腳本生成的。發現是Pythondir的配置不對：
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
改過來就OK了
