Re: compiling GR 3.10.5.1 with ENABLE_GR_SOAPY=ON

[Ron Economos]

You can also try adding:

-DCMAKE_FIND_DEBUG_MODE=ON

to your cmake invocation. This will dump where cmake is trying to find 
package files.

If you really get stuck, it may be useful to use a more common install 
prefix. Cmake will default to /usr/local and /opt.

I'm a big fan of using /opt. It's very easy to delete installs in /opt 
versus /usr/local.
