Questions about Fitipower FC0012 tuner + rtl_433 support

[NJ]

gqrx has really simplified my first try at SDR: THANK YOU to everyone of you involved in this project.

I noticed that the RTL-SDR dongle that I have (which uses the Fitipower FC0012 tuner) does not run at all on version gqrx 2.11.5: i only get static output.

$ /Volumes/gqrx-2.11.5/Gqrx.app/Contents/MacOS/rtl_test

    Found 1 device(s):

      0:  Realtek, RTL2838UHIDIR, SN: 00000001

    Using device 0: Generic RTL2832U OEM

    No supported tuner found

    Enabled direct sampling mode, input 1

    Supported gain values (1): 0.0

However, when using gqrx 2.5, I am able to tune in to radio stations as expected

$ /Volumes/gqrx-2.5-1/Gqrx.app/Contents/MacOS/rtl_test

    Found 1 device(s):

      0:  Realtek, RTL2838UHIDIR, SN: 00000001

    Using device 0: Generic RTL2832U OEM

    Found Fitipower FC0012 tuner

    Supported gain values (5): -9.9 -4.0 7.1 17.9 19.2

This leads me to believe that gqrx 2.11.5 dropped support for the FC0012?

So my questions are:

1. What do I need to do to add support for the FC0012 back into gqrx 2.11.5, at-least for my local build?

2. What do I need to do to get the rtl_433 tool into the set of the tools available with gqrx 2.11.5? I purchased the RTL SDR dongle to help me replicate my light and outlet switches and I believe the rtl_433 tool will be very valuable
