How to correctly import freenect2 using cmake?

Question

I have to use a kinect2 (ubuntu 16.04 LTS). So I installed several things :

• OpenNi (https://github.com/OpenNI/OpenNI)

• OpenNi2 (https://github.com/occipital/openni2

• libfreenect, (because I used the first kinect before) (https://github.com/OpenKinect/libfreenect)

• libfreenect2 (https://github.com/OpenKinect/libfreenect2)

• PrimeSese (with the corresponding part of https://www.icyphy.org/accessors/wiki/Main/InstallingThePrimeSenseKinectSensorOnUbuntu)

• OpenCV (https://github.com/opencv/opencv)

When I was using the first kinect I was able to import the libfreenect tools without an problem, but now way with libfreenect !

You can find my CMake here. There isn't any problem with the others libs in the CMake.

What I changed to install libfreenect2:

• I clone the repository in my folder ~/sofware. (I put all my libs here)

• Instead of

  cmake .. -DCMAKE_INSTALL_PREFIX=$HOME/freenect2
  

  I did

  cmake .. -DCMAKE_INSTALL_PREFIX=$HOME/software/libfreenect2/freenect2
  

With my Cmake when I compile I got this:

CMakeFiles/Kinect2CaptureYM.dir/app/Kinect2CaptureYM.cpp.o: In function `Kinect2CaptureYM::Kinect2CaptureYM()':
Kinect2CaptureYM.cpp:(.text._ZN16Kinect2CaptureYMC1Ev[_ZN16Kinect2CaptureYMC1Ev]+0x108): undefined reference to `libfreenect2::Freenect2::Freenect2(void*)'
Kinect2CaptureYM.cpp:(.text._ZN16Kinect2CaptureYMC1Ev[_ZN16Kinect2CaptureYMC1Ev]+0x427): undefined reference to `libfreenect2::Freenect2::~Freenect2()'

collect2: error: ld returned 1 exit status

make[1]: *** [CMakeFiles/Kinect2CaptureYM.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....

So my make isn't able to link the the freenec2 lib. But I don't understand why as I put this in my makefile:

FIND_PACKAGE(freenect2 REQUIRED)
LIST(APPEND INCLUDE_DIRS ${FREENECT2_INCLUDE_DIRS})
LIST(APPEND LIBRARIES    ${FREENECT2_LIBRARIES})

Does someone know how to link it correctly ? I'm really stuck beacause of that :/

If you need anything else just ask, thx!

PS : The most important things in my code are (enough to make the make crash):

• the include : #include <libfreenect2/libfreenect2.hpp>
• the declaration : libfreenect2::Freenect2 freenect2;
