Installing SoapySdr modules for RTL-SDR or AirSpy

I am trying to build and run the simple example for SoapySdr as found here https://github.com/pothosware/SoapySDR/wiki/C_API_Example. I can use the SDR with Gnuradio but that doesn't work for my application (reason not relevant). I get the simple program to compile but when it runs it doesn't see any devices. Running

SoapySDRUtil --info

    ######################################################
    ##     Soapy SDR -- the SDR abstraction library     ##
    ######################################################

Lib Version: v0.8.1-gbb33b2d2
API Version: v0.8.200
ABI Version: v0.8-3
Install root: /usr/local
Search path:  /usr/local/lib/SoapySDR/modules0.8-3 (missing)
No modules found!
Available factories... No factories found!
Available converters...
 -  CF32 -> [CF32, CS16, CS8, CU16, CU8]...

No modules found and no factories found. For me the hard part is getting a time series stream from the device. I can do whatever processing I need on that stream. So, I just need to get this simple example to run. I've tried a number of installs such as sudo apt-get install rtl-sdr soapysdr-module-rtlsdr but nothing seems to change the result. When I compile and run the example (I added a print statement to output the number of Soapy SDR devices found) I get this:

gcc -std=c99 example.c  -lSoapySDR && ./a.out
Found 0 devicesSoapySDRDevice_make my fail: SoapySDR::Device::make() no match

In my case I solved my issue by downloading:

https://github.com/pothosware/SoapyRTLSDR/wiki#building-soapy-rtl-sdr

and remove

sudo rmmod dvb_usb_rtl28xxu
sudo nano /etc/modprobe.d/rtl-sdr.conf
blacklist dvb_usb_rtl28xxu
