Confirm linux64 and linuxarmv7l

@NickHardeman and I have done a cleanup to ofxKinectV2 - going back to using the libfreenect source to make it easier to build for mac and windows.

Both mac and windows build fine now with the projectGenerator.
Could you check on Linux and see if anything needs adding to addons_config.mk?

Lots of nice new features like ofxKinecV2::Settings which allows for streams to be toggled on and off and max depth range to be changed.

Hi. I have followed the amazing tutorial by @madelinegannon https://gist.github.com/madelinegannon/10f62caba7184b90ea43a734768e5147 and I was able to run the ./bin/Protonect executable.

I have installed OF and compiled with gcc-6. I have added these lines to my .bashrc file (and I hame made sure that cuda was correctly installed and that /usr/local/cuda is the correct location).

export LD_LIBRARY_PATH="/usr/local/cuda/lib64:${LD_LIBRARY_PATH}"
export LD_LIBRARY_PATH="/usr/local/lib:${LD_LIBRARY_PATH}"
export PATH="/usr/local/cuda/bin:${PATH}"

When I run the example provided in this repository, I receive the error:

/usr/bin/x86_64-linux-gnu-ld.gold: error: cannot find -lfreenect2
/usr/lib/gcc/x86_64-linux-gnu/6/../../../x86_64-linux-gnu/Scrt1.o:function _start: error: undefined reference to 'main'
Sources/of_v20200227_linux64gcc6_release/addons/ofxKinectV2/libs/libfreenect2/src/packet_pipeline.cpp:42: error: undefined reference to 'libfreenect2::VTRgbPacketProcessor::VTRgbPacketProcessor()'
collect2: error: ld returned 1 exit status

and actually there is no libfreenect2.so in /usr/local/lib.

Any clue? I think that libfreenect2 is probably not installed system wide, so the Proton example works, but the OF app no.

Just as a side note, I had make a mistake while installing libfreenect2. The instruction reported by @madelinegannon are correct, just:

> mkdir build && cd build
> cmake -DBUILD_SHARED_LIBS=ON ..
> make
> make install

needs to be

> mkdir build && cd build
> cmake -DBUILD_SHARED_LIBS=ON ..
> make
> **sudo** make install

Otherwise it can not install the library system wide.
The example application provided in works in the .
I have copied that example found in https://github.com/madelinegannon/ofxKinectV2 in this repository.

I have removed all the libraries in addons/ofxKinectV2/libs except of protonect.
I have run make && makeRunRelease and the example worked.

Thanks Davide! We can take a look and see what's in Madeline's example that we can add or do a example-linux as suggested.

The only two steps to get the example working on linux (after installing cuda, libfreenect2, etc, as explained in the guide) are:

• Add PROJECT_LDFLAGS=-L/usr/local/lib/ -lfreenect2 -L/usr/local/cuda/lib64 -lcuda -lcudart to config.make
• Delete everything except protonect in ofxKinectV2/libs

Then if you run make && make RunRelease it works

Awesome! Thank you!
