The old configure script seems slightly more useful re libatomic_ops
(i.e. probably not needed on native x86 builds).
I'm not sure that I would call them 'bindings' for cmake, but I can
see that cmake can use them to find things (until I read your reply
I was going to say it was for things built by cmake). But then I'm
fairly vague on the uses of 'binding' (apart from linking footwear
to ski).
Thanks for pointing to these. I have cmake files for clang, DBus1,
fftw3, harfbuzz, libxml2, llvm, PulseAudio, SDL2 and some of those
were definitely NOT built by cmake - I suppose they saw cmake was
installed and tried to play nicely with it.
Will commit shortly (I suppose docbook-xml, docbook-xsl and libxslt
need to be kept as a group, so libatomic_ops ought to go after all
three, not before where I initially put it).
