Thank you for the patch! Could you please check that about the CLA? (See automatic comment)

Also, seems it uses locally installed Boost. Which would be anyway not so trivial to compile in an example :)
We should probably add a comment about that..

testing CLI check

It seems that you attached the testing commit which you did not intent to include in pull request :)

Also, please sign the CLA, I can not merge the pull request without that.

CLAs look good, thanks!

Whoops, reset that last commit. Updated the author to match the email with which I signed the CLI, and added a comment about dependency on locally installed Boost.

Any advice on how to get rid of that local dependency?

[irengrig]

I created a pull request to your fork with building boost.

Also, seems that we are using different versions of CMake, can not think of other differences - but for me it works only if I specify EIGEN_INCLUDE_DIR and FLANN_INCLUDE_DIR, not DIRS variant.
Lets keep both variants, it does not affect anything.

I was able to build the target in 4500 seconds :)

Cool, we did it!
