I had luck compiling qt-5.11.0 and most of the KDE5 foundation
up until kservice. I think I reported the error before already
but I'll report it again, since this is now with
kservice-5.4.60.

The error is:

---------------------------------------------------------------

CMake Error at autotests/CMakeLists.txt:47 (file):
  file COPY cannot find
  "/Depot/Temp/kservice-5.46.0/autotests/fakeplugin.desktop".


CMake Error at autotests/CMakeLists.txt:48 (file):
  file RENAME failed to rename

    /Depot/Temp/kservice-5.46.0/autotests/fakeplugin.desktop

  to

    /Depot/Temp/kservice-5.46.0/autotests/fakeplugin_json_new.desktop

  because: No such file or directory

---------------------------------------------------------------

I do not know why it can not find/copy the fakeplugin.desktop
file. Would it be possible to try to continue even if it
can not find that file? Or does kservice really depend on
it.

I'd love to be able to compile the rest of KDE5 including KDE
Konsole but kservice stops me from doing so right now.
