You're welcome. 

It's really easy… if you're a programmer who uses cmake every day. 
I would expect projects to put this info into the readme file (and most
do), but apparently they didn't think that users might want to compile
it? 

I have been doing so.

Excellent! Many thanks, kind Sir!

Aside: how much training and experience would be needed to reach that

Peter,
   I'm no expert at this but a year ago I wanted to try fixing a few bugs
in the KDE solitaire game and was faced with understanding and building the
code. After numerous problems like yours above I ended up deciding I needed
a development environment and chose KDevelop. Once I did that, with a
little more study, I was able to build the program and run it. You might
give something like that a try.

   On the downside, KDevelop is pretty big and heavy. I don't know how the
updates run on that program but building it would likely be a bit of a time
sink if you don't already have it installed and then keeping it updated
could possibly be more time. On Ubuntu it's a non-issue.

Good luck,
Mark

Don't run cmake in src/, run it in the directory src is in.

appstreamcli is in dev-libs/appstream.

# This configures the build (checks for dependencies and so on)
cmake -S . -B build 
# This compiles the sources
cmake --build build

The binary is in ./build/src/kdfm – you can install it globally with 
sudo cmake --install build

Kind regards, tastytea

Okay, I did that. It ran for much longer, and threw no errors, and once again 
it ended with 'Build files have been written to: /usr/local/src/kdfm-code/src'. 
Then:

wstn /usr/local/src/kdfm-code # cmake ./src
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-
root'
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-
root'
-- Could not set up the appstream test. appstreamcli is missing.
[...]
-- Configuring done
[...]
-- Generating done
-- Build files have been written to: /usr/local/src/kdfm-code/src

Google hasn't helped with appstreamcli being missing.

Have the build files been written or not? What do I do with them?

You need to run cmake in the directory that has the top-level
CMakeLists.txt. Use cmake -S . -B build from the top-level directory.
This whill use . as source directory and build as build directory.
You will need kde-frameworks/extra-cmake-modules.¹

Kind regards, tastytea

Minor point, I would recommend creating a build subid, cc into it and 
the "cmake path-to-source-dir".  I think most KDE stuff doesn't like 
building in-tree.  Equery doesn't identify any package for qt5_wrap_ui.  
If it's part of the source, then you might need some parameter for 
cmake, or else there's another dependency not packaged in Gentoo.

Hello list,

I wanted to try KDFM, which I read about in Linux Format. It's a file manager 
with some interesting features. So I went to sourceforge.net/projects/kdfm, 
downloaded the source and extracted it to /usr/local/src/kdfm-code.

What do I do next? I tried 'cmake ./src' and similar and got Unknown CMake 
command "qt5_wrap_ui". Googling for that found a few helpful pages, but I 
think I'd need to be a Qt5 developer to understand them.

Can anyone point me in the direction to find out what to do?
