The executable of the ninja-build package is installed as "ninja-build" instead of the upstream default "ninja". Please rename it back. 1. The reason for the renaming was a conflict with the ninja IRC client, however that project did not have a release for many years, and it is also no longer available in Fedora 22. 2. All other major distros (openSUSE, Ubuntu, Debian) ship the binary as "ninja". 3. The renaming breaks at least the detection of ninja-build in CMake.
CMake has patches to detect ninja-build (in Fedora originally, but I pushed them upstream). I'll have to do the FESCo dance to get the Conflicts: added (just because it is retired doesn't mean it leaves existing machines).
(In reply to Ben Boeckel from comment #1) > I'll have to do the FESCo dance to get the Conflicts: added ... Is this discussion public?
No, I haven't started it. *** This bug has been marked as a duplicate of bug 1166135 ***
