Had to recompile with:

cmake ../ -DINSTALL_UDEV_RULES=ON -DDETACH_KERNEL_DRIVER=ON

before it worked.
Just sharing as it might help someone else as well.
Thanks for this posting!

This is still relevant in 2022

Compiled it same way, but got message No supported devices found. I already tried compiling and installing driver for rtl sdr many different ways, but with no luck. I have no idea at this point what I am doing wrong. Could it be caused by Raspberry OS 64-bit system?

EDIT: It works now, problem was in crappy USB extension cable.

2024 here. You might have to use this link below instead of the git link posted in the instructions:
git clone https://github.com/osmocom/rtl-sdr.git

Thanks. It looks as if the canonical repo has moved to Gitea: https://gitea.osmocom.org/sdr/rtl-sdr.git but there is an official mirror on Github: https://github.com/osmocom/rtl-sdr.git. I'll update the instructions accordingly.
