make install做了什么
如上所示，可以看到install将动态库放到了/tmp/usr/local/lib/libserial.so里边
头文件放到了tmp/usr/local/include当中了
如下所示

cd build && make install
make[1]: Entering directory '/home/yuhs/novatel_ws/src/serial/build'
make[2]: Entering directory '/home/yuhs/novatel_ws/src/serial/build'
make[3]: Entering directory '/home/yuhs/novatel_ws/src/serial/build'
make[3]: Leaving directory '/home/yuhs/novatel_ws/src/serial/build'
[ 66%] Built target serial
make[3]: Entering directory '/home/yuhs/novatel_ws/src/serial/build'
make[3]: Leaving directory '/home/yuhs/novatel_ws/src/serial/build'
[100%] Built target serial_example
make[2]: Leaving directory '/home/yuhs/novatel_ws/src/serial/build'
