Description Aoife Moloney 2025-07-03 09:26:28 UTC 
This is a tracking bug for Change: CMake: Use ninja generator by default
For more details, see: https://fedoraproject.org/wiki/Changes/CMake_ninja_default

Change the default generator used in the %cmake macro from make to ninja. Affected projects are tracked in this copr repo, please check if your packages are failing there.

If you encounter a bug related to this Change, please do not comment here. Instead create a new bug and set it to block this bug.
Comment 1 Aoife Moloney 2025-08-19 21:12:07 UTC 
Dear change owner, this is a reminder that your change is required to be 100% code complete by August 26, which is the start of beta freeze. Please provide a status update on your change in the Incomplete Changes Report if you are not able to move your change to 'ON_QA' before this date. If you need to defer your change to the next Fedora release, please let me know and I will reassign this bug and the change page. Thank you kindly.
Comment 2 Cristian Le 2025-08-21 16:18:37 UTC 
Would probably need to push this to F44 since it would still require quite a few PRs to be created. I will try to automate push a bunch of PRs, but it would be too much pain to make beta freeze exceptions for each package, so better to push it back to F44 instead.
Comment 3 Aoife Moloney 2025-09-01 13:53:08 UTC 
Reassigning this change to F44 as per FESCo decision https://pagure.io/fesco/issue/3465
Comment 4 Allison King 2026-02-03 19:37:47 UTC 
Hi fedora, how goes this change for F44? The testable deadline is today, February 03, 2026, and changes need to be in good shape at this point https://docs.fedoraproject.org/en-US/program_management/changes_policy/#_change_process_milestones

Please let me know if you need to defer this to F45, otherwise if you're good to go for the change to be ready to meet the testable requirements, please update the status of the tracker bug to MODIFIED.

Thanks!

Comment 9 Jens Petersen 2026-02-24 06:19:42 UTC 
Seems this landed rather late?

It breaks building lean4 unfortunately, as reported in https://github.com/leanprover/lean4/issues/12575

Alright I should have read the page I guess...

%global _cmake_generator "Unix Makefiles"

seems to unblock me.
