I get a problem compiling drkonqi from source on Linux.

Before I describe the error, allow me to show you my OS and relevant software versions, so that you can exclude some errors:

  Binutils Version:                GNU gold (GNU Binutils 2.31.1) 1.16          
==

This was a slackware system but I compiled most everything from source myself,
excluding glibc and kernel (which are a bit old, but the rest is up to date,
including binutils).

I compiled most of the KDE stack recently, KDE apps and KDE foundation (well,
for the most part, up to the dependencies of drkonqi). This worked very well.

The source tarball I am using is this one here:

  https://download.kde.org/stable/plasma/5.13.5/drkonqi-5.13.5.tar.xz

drkonqi, however had, has a problem, which will be shown next:

It seems to want to create a symlink; before so, it wants to remove an existing
path which is a directory. I am not sure why but I believe that there is some
error with the directory-path there.

I'll next display more of the error - perhaps it helps. (I am using some ruby
scripts to automate the compile-process; that is why the copy/pasted text
below has a few different messages perhaps. Oddly enough, drkonqi has some
ruby components too and these do not seem to work reliably right now and
do not seem to be rescued; I suggest a begin/rescue clause additionally,
and a meaningful error message if rescue fails. But this is not the reason 
for the cmake-problem shown above; just something I also wanted to mention.)
