muse FTBFS on rawhide. RHBZ#1923460 The reason is a change in the atkmm-devel package, which includes the header atkmmconfig.h in a nonstandard location /usr/lib64/atkmm-1.6/include/ cmake needs to be taught about this header file. The fix for the upstream tracker fixes this issue https://gitlab.kitware.com/cmake/cmake/-/issues/21627 Can you please backport this fix so we can build muse? I tested it in local mock and it works.
Fix should be included since at least https://bodhi.fedoraproject.org/updates/FEDORA-2021-e91fa263c5
