cmake not finding the soapysdr directory

[waterwin]

Building in a Ubuntu 18.04 VirtualBox on Solus Linux. Solus host, Ubuntu client.
Built all Sophos and Soapy materials and libiio and libad9361

But cmake throws error that SoapySDR can not be found.
Did not change any paths from the standard install.

I will now try SoapySDRplay install to see if same is happening.

Install soapysdr first

It even looks as if I did not install SoapySDR at all (my bad).
I have now installed SoapySDR and running cmake .. from ~/SoapyPlutoSDR/build has new errors.
libiio not found. I did install libiio and libad9361 from the deb packages on the AD website for Ubuntu Bionic Beaver(v 18.04) which was handled via the standard Ubuntu package manager. As that is where the 2 links for these 2 dependencies take me.

libad9361.so is in /usr/local/lib whereas libiio is in /usr/lib/x86_64-linux-gnu

I will now build these 2 from source to see if that makes any difference.
Or maybe should try an install with gdebi first.
Or try one of the other simpler modules first like the RTL-SDR
As currently: SoapySDRUtil --info gives
Search path: /usr/local/lib/SoapySDR/modules0.8 (missing)
No modules found!
There even is no SoapySDR folder there.

After build from source of SoapySDR and Pothos and the modules all without errors or warnings. Not found in Pothos GUI, both devices not found usable in GQRX, no blocks for these 2 devices in GNUradio. I am at a loss now. Pothos test is 131 x success. All other tests see below, all looking good to me.
One path is modules0.8 (install) the other modules0.7 (search) which is odd (not Ood).
