ROSBUG:libopencv_imgcodecs3.so.3.3.1: undefined reference to `TIFFReadDirectory@LIBTIFF_4.0`

ROS安装完后会安装一个opencv，但是自己也安装了一个opencv, 于是可能这两个opencv可能就产生了冲突。ROS默认调用的是自带的opencv。
解决办法：
查找libopencv_imgcodecs3.so.3.3.1依赖的库：

ldd /opt/ros/kinetic/lib/x86_64-linux-gnu/libopencv_imgcodecs3.so.3.3.1

输出：

linux-vdso.so.1 =>  (0x00007ffd3bb9b000)
libopencv_imgproc3.so.3.3 => /opt/ros/kinetic/lib/x86_64-linux-gnu/libopencv_imgproc3.so.3.3 (0x00007f81bcc53000)

libtiff.so.5 => /usr/lib/x86_64-linux-gnu/libtiff.so.5 (0x00007f81bc0e7000)  //看这里
libjasper.so.1 => /usr/lib/x86_64-linux-gnu/libjasper.so.1 (0x00007f81bbe92000)
libopencv_core3.so.3.3 => /opt/ros/kinetic/lib/x86_64-linux-gnu/libopencv_core3.so.3.3 (0x00007f81baf58000)

librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f81b9897000)

然后在CMakelist.txt中手动指定tiff的路径

  target_link_libraries(${PROJECT_NAME}_lib
  	...
    /usr/lib/x86_64-linux-gnu/libtiff.so.5  
  )
