[Issue] References to `-DFLANN_INCLUDE_DIR_HINTS` are obsolete?

[MeirArani]

The INSTALL.md documentation currently references this option:

For FLANN library, FLANN_INCLUDE_DIR_HINTS can be passed pointing to the include directory, e.g. -DFLANN_INCLUDE_DIR_HINTS:PATH=/path/to/flann/1.8.4/include/

But the relevant file which handled this logic (findflann.cmake) was removed in #1495 right?

I was trying to make use of the option, but it was having no effect. I tried digging for references to the flag in the source code, and found absolutely zero. Does this mean we should update the documentation to reflect this? Or am I missing something here?

Hi @MeirArani,

The documentation indeed needs to be updated, this is a work in progress as we're moving towards the release. Thanks for the heads up!
