At final Link library problem

[speed8928]

Hi
I tried to use opencv3 to build the system. I have success to build up DBoW. I have changed some source that related to SURF detector( that is pointer in opencv3). But, at target_link_libraries, it stops for some reasons I couldnt be able to figure out. If anyone know it?
My system is Ubutun 16.04. I used OpenCV 3.4.5 and PCL 1.8.

I solved it by reinstall opencv 2.4.9 form https://github.com/lakehanne/opencv-2.4.9 and specify all dependencies with this opencv and follow the installation guide with this page https://github.com/HTLife/Kintinuous-installation-guide/blob/master/Kintinuous-installation-guide-16.04.md
