Bug description

A am looking to rebuild nextcloud.exe with some code changes as a drop-in replacement file for the Windows Nextcloud 3.12.x Client as installed from https://github.com/nextcloud-releases/desktop/releases, that is, keeping all external dependencies like Qt5 unchanged. Given that the many dependencies are intimidating, I was hoping to leverage an existing CI to create a test build.

I am using Github Actions in a fork, which does work in principle, but fails specifically on the stable-3.12 branch: both macOS and Windows fail with build system bugs.

Given that the branch is still actively receiving backports, I wonder if you intend to maintain them in a working condition?

Anyway, my personal motivation for reporting this is to find any working CI to obtain a patched release binary to validate fixes for #7166 in the field without investing a day or three building my own build environment.

1. macOS Build and Test / macOS Build and Test (pull_request) fails:

CMake Error: The source directory "/Users/runner/work/nextcloud-desktop/nextcloud-desktop/downloads/git/dev-utils/kshimgen" does not exist.

1. Windows Build and Test / Windows Build and Test (pull_request) fails in step Install Craft Master with Nextcloud Client Deps:

Steps to reproduce

One way is probably for a maintainer to re-run the GitHub Actions.

Another way:

1. Fork nextcloud/desktop to a personal account
2. Checkout stable-3.12
3. Branch to stable-3.12-test and commit some insignificant change
4. Maybe remove most of the .github/workflows except Windows and macOS related
5. Create pull request from stable-3.12-test into stable-3.12
6. Watch the CI steps fail after some 30min-50min

Expected behavior

CI jobs would pass.

@cluck may I ask why you are trying to build 3.12 branch ?
You have probably noticed that at least regarding build macOS and windows github actions are building fine in other stable branches

[cluck]

I am tracking all 3.12, 3.13 and 3.14 branches here: https://github.com/cluck/nextcloud-desktop/pulls

3.12.7 is the most recent release on Windows which we have tested toroughly, which there are no reports of it crashing and we're not aware of the UI being broken. We have a large fleet and are evaluating updates carefully.

Btw. the 3.13 branch also fails to build.

@cluck there is no issue building 3.12, 3.13 or 3.14 branches
there is an issue with the CI windows workflow because no one had time to make it work with the qt5 branches for KDE's Craft and craft blueprints
manual setup of the dependencies is obviously working or we could not do any release.
there is nothing secret or hidden there
anyway, this is not a bug but a request for support
can you please move to the Nextcloud forum (https://help.nextcloud.com) ?
