How to correctly import freenect2 using cmake? - c++

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
CMakeFiles/Kinect2CaptureYM.dir/build.make:156: recipe for target 'Kinect2CaptureYM' failed

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;
