I have one build failure unrelated to yaml-cpp for a package I don't maintain, supercollider:

In file included from /usr/include/sndfile.h:6,
                 from /builddir/build/BUILD/SuperCollider-3.12.2-Source/server/plugins/DiskIO_UGens.cpp:27:
/usr/include/sndfile-64.h:356:33: error: conflicting declaration 'typedef struct sf_private_tag SNDFILE'
  356 | typedef struct sf_private_tag   SNDFILE ;
      |                                 ^~~~~~~

      |                            ^~~~~~~

And OpenColorIO 2.2.0 apparently also needs minizip-ng 3.0.6 which isn't yet in Rawhide...

Thanks,
