hooohh… please, please, ramble on!!! You are very welcome! :-D

Well, the QSP patch is there to run a KDE-Linux/CI-compatible OSX/CI system, for nothing else!!!
As Thiago wrote: if we want to introduce a new feature, like XDG paths on OSX, then it is another issue.
That could be accepted as new contribution for Qt5, but our KDE-internal OSX/CI-patch won’t get accepted
which is very understandable.

That’s just great news!

Well, since you managed it so well, perhaps you can update the corresponding wiki page  which is quite
outdated (from 2012) and seems quite overloaded to me?! I think this might be very helpful for followers!
This page is shows on  in the section “Installing using MacPorts” and should surely mention that the
"development environment" is “kdesrc-build development environment”, I believe.

Well, I thought, it should be doing that! :-(

The OSX/CI system doesn’t need these tweaks, but that’s due to the fact that all the installations are in their
own install roots and the XDG_*_DIRS point to it properly.
Good to know that you spotted this, as this requires an adaption of the CMake build system for OSX.

Same thing as above.

kdeedu-data is a separate project, which these two apps should depend on, if they want to share data.
If that is the case and the dependency is properly defined in the kde-build-metadata repo then the
OSX/CI system will allow such sharing, just like on Linux.
Funny thing is, that here on the CI system I don’t see any dependency on it:
grep kdeedu-data dependency*
which is a bit weird.
Well, I just build it on my OSX/CI system:
$ ./install.sh kdeedu-data
Project : kde/kdeedu/kdeedu-data
Branch : master
Linux-CI : -
Creating still missing build directory...
Build... : SUCCESS
So, the next step would be to include this in
$ git diff
diff --git a/dependency-data-kf5-qt5 b/dependency-data-kf5-qt5

Shall I commit this change?
BTW, khangman showed its main window fine, let me guess the 1st word, drew happily the gallows and I
struggled to not get hanged which I failed because of “hedgehog”
This means: KHangman is the first word game that WORKS on OSX/CI somehow better then others,
although it still claims to not have found one file and the icon theme:
Menu "applications-kmenuedit.menu" not found.
Icon theme "hicolor" not found.
kf5.kiconthemes: "Theme tree: (Oxygen)"
I don’t know whether the last line means that it has successfully located the oxygen them or not.
I was able to switch the background themes, no problem.
But when I leave the app then it crashes with a segfault. (Let me know if you’re interested in the crash log.)
After restarting the app again I even see all menu items in the main menu instead of only “khangman”.
Downside is that the app consistently crashes at exit.
In the “Preferences” dialog I see that all the icons are indeed missing.

Well, yes, all this is a complicated matter, especially since you’d have to share a lot of files, not only those
kdeedu-related files, but ALL KDE libraries and stuff would have to be shipped as well, if you don’t use a
system like MacPorts, but want to go to the AppStore and intend to build self-standing application packages
which should be drag-droppable wherever the user wants them to put...

Wow, yep, I don’t have sound here on OSX/CI either… :-(

White squares? Hmmm…

… I don’t see this. As written in PM I have very bright buttons with a faint shadow of the arrows. If I click
the button the background becomes darker and I see the bright arrow better.
So, it could be that this is due to your VirtualBox rendering.
I could send you a screenshot of my OSX/CI’s kanagram, if you want.

The window title bar is empty here, but probably because my kanagram can’t find its files anyway atm.

I hope this and my PM post help to let us get further with all this.
I think you made amazing progress and I am confident now that we’ll now be able to straighten out all the
CMake configuration options of many projects currently leading to trouble finding data and config files on
the OSX platform. :-)
