            Bug ID: 404487
           Summary: When building Qt 5, global make options are ignored
           Product: kdesrc-build
           Version: Git
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: mp...@kde.org
          Reporter: jm.ouwerk...@gmail.com
  Target Milestone: ---

SUMMARY
When building Qt 5 with kdesrc-build, the global make options appear to be
ignored. This manifests itself in noticeably less fan noise than expected when
you configured a global `-j12` but effectively get `-j1`. It also takes a lot
longer.

STEPS TO REPRODUCE
1. On fresh system without Qt set up kdesrc-build
2. Make sure to include kf5-qt5-build-include and qt5-build-include
3. Run kdesrc-build qt5

OBSERVED RESULT
On an 8-core CPU, the load as reported by ksysguard stays effectively pegged at
~ 12% (i.e. ~ 1 core)

EXPECTED RESULT
I expect the CPU to be given a bit more of a workout with a load of roughly
~100%.

ADDITIONAL INFORMATION
This issue can be worked around by manually configuring kdesrc-build.rc with:

```
options qt5-set
    make-options -j12
end options
```
