compiling stript-it error. Please help me check which lib should be added and how to add the lib

[Zheng Zhao]

step 1: cmake

OpenBabel include directories: /home/localadm/source/openbabel-install/include

OpenBabel link library: /home/localadm/source/openbabel-install/lib/libopenbabel.so

Installation directory of executable: /home/localadm/source/strip-it-1.0.2/bin

-- Configuring done

-- Generating done

-- Build files have been written to: /home/localadm/source/strip-it-1.0.2

step 2: make
