Description
Is your feature request related to a problem? Please describe.
FLANN library is not maintained anymore, it hardly had any commit since April 2019, as mandatory dependency for PCL It just seems a bit odd.
People have brought this issue in the past at least once: https://github.com/PointCloudLibrary/pcl/pull/84
Describe alternatives you've considered
No one around here is not unfamiliar with the direct fork https://github.com/jlblancoc/nanoflann, that offers better performance and flexibility.
I am curious whether people have ever considered this ? would we face any problems ?
A complete port is no small feat, but I would be happy to help.

Research direction
This is a discussion about replacing the unmaintained FLANN dependency with nanoflann; no files, tests, or entry points are named. Start by reviewing the prior PCL pull request #84 and nanoflann, then determine whether a complete port is feasible and what problems it would introduce. Done would require an agreed migration plan, not a defined patch.
