Thanks - and now I know C11 is required too.

It would be nice to have something easily found by a human, from the
top-level README, that sets out the requirements, in an OS-independent
way. I had searched for this and not found it. When packaging, I like
to align the package config files to the upstream documented
requirements, rather than fiddling until it builds, to make it more
likely it will be ok on some other system.

In theory I know that, but I couldn't find it in the cmake output.
(It's also a general bug of cmake to hide build lines by default :-(
which makes this harder.)

How does building gr-osmosdr work? I don't see that it requires C++17
(because it's in C++11 itself), but if the compiler isn't in C++17 mode
it will object to gnuradio's headers.
So I think I need to in our "buildlink" file (that you include when you
want to link against stomething) for GNU Radio add a setting to force
c++17 mode.
My cmake output follows, and I don't see about testing if the compiler
supports C++17.
