Created attachment 575482 [details] full build log FWIW I've no idea how this is triggering a bug and I suspect it's upstream, but hoping you can at least confirm and maybe explain what deep magic is going wrong here. I currently have libkdegames-9999 at upstream commit 4bf270e37 installed, and I just tested using EGIT_OVERRIDE_COMMIT_LIBKDEGAMES that it still merges just fine. As of now there's a single additional commit to upstream, 9de5c8264, and that does NOT build. But it's simply a required cmake version bump (paste mangles spacing a bit): commit 9de5c0264 (HEAD, refs/git-r3/kde-apps/libkdegames/5/__old__, refs/git-r3/kde-apps/libkdegames/5/__main__, refs/git-r3/HEAD) Author: Laurent Montel <montel@kde.org> Date: Tue May 7 13:52:01 2019 +0200 GIT_SILENT:It's time to increase cmake version too --- CMakeLists.txt | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 0cff85c4a..9b711ab0c 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -2,7 +2,7 @@ enable_testing() project(libkdegames) -cmake_minimum_required (VERSION 2.8.12 FATAL_ERROR) +cmake_minimum_required (VERSION 3.5 FATAL_ERROR) set (QT_MIN_VERSION "5.3.0") find_package(ECM 1.3.0 REQUIRED NO_MODULE) Looks innocuous, right? And that same cmake required version bump has been applied (probably scripted, actually) across many upstream packages that continue to build just fine! So what's different about libkdegames that makes it break there?

But why is a should-be-innocuous bump in cmake_minimum_required triggering it? FWIW cmake-3.14.3 installed (well above the 3.5 required bump), and just in case it makes a difference I just upgraded to gcc-9.1.0, but as I said, I tested by rebuilding the previous commit with the now-current toolchain and it worked fine, so what sort of deep magic is breaking, here? The only thing I can guess is that the previous cmake_minimum_required 2.8.12 triggered some sort of cmake-2.x old-cmake-compatibility mode that the new cmake_minimum_required 3.5 doesn't, or perhaps it's the 2-vs-3-component version difference, but either way, one then wonders why the same change in other packages isn't breaking them as well? Makes no sense at all to me, but maybe it will to you...
kde5.eclass modifies CMakeLists.txt re USE flag settings, so it is a downstream issue triggered by cmake behavioural change.
