Yes - sorry I had patched that to lower case as a test but only after 
testing and hitting this issue - it was late :\

This is the actual error unpatched:

  Could not find a package configuration file provided by "Gnuradio" 
with any
  of the following names:

    GnuradioConfig.cmake
    gnuradio-config.cmake

OK fixed that. Because we don't have a gnuradio-devel package I put the 
gnuradio cmake files in gnuradio-utils instead - was not important at 
the time as they were not used. That error goes away with gnuradio-utils 
added to BRs.

So getting a little further but now we have:

------------------------------

We do have these installed in the build chroot:
BuildRequires:  gmp-devel
BuildRequires:  gmpxx-devel
BuildRequires:  mpir-devel
BuildRequires:  mpirxx-devel

But I don't understand:
--   Found gmp, version 6.2.0
-- Could NOT find GMP
