Hello Samuel, Time to make an NMU of cmake. The needed patches are now committed upstream, see below: From: Brad King <gitlab at gitlab.kitware.com> Subject: Re: CMake | Port to GNU Hurd (#18337) AFAIK the only changes were 3c0bfb59 and c990649b. The former is already in 3.12.3. The latter will be in 3.13.
