Why did you rename the folder. You can already build the demo by default.
Well, if I would have been able to build the demo, I wouldn't have created a complete new project.
Second reason: it was the question where the demo app is, you have to search it in src. Whereas the examples are in the root - why have two different concepts?

That is not good engineering, first you should understand the problem.

It's not an example it's a standalone application that is installable.
The problem is, that I check out a completely unknown fresh new project, try to compile it, and it does not work. I did neither change nor remove something. So what do you guess I should do? Go on, try another project?

Open an issue with the error and ask for help maybe.

I know that make install of fluid copies the plugin into the Qt folder. I have no idea where this demo should be.

Doesn't say much just that you can't build it but you don't say what is your problem. README.md documents how to build Fluid and the demo gets built automatically by default.

Why would I want to have a demo in $QTDIR/bin? But... Qt/5.14.2/gcc_64/bin/ does not have the demo, Qt/5.14.2/gcc_64/qml has no bin, Qt/5.14.2/gcc_64/qml/fluid has no demo... where else could it be? which fluid-demo -> fluid-demo not found

This is true, sorry for that

You don't, it's installed in $CMAKE_PREFIX/bin

Make sure submodules are fetched:
git submodule update --init
Then following the instructions at https://github.com/lirios/fluid#build we see that the -DFLUID_USE_SYSTEM_LCS:BOOL=OFF option needs to be passed to cmake in order to use LCS from the git submodule.

I have added more information on the build process: https://github.com/lirios/fluid/commit/24a57c6832164e40e364d2ef5d29d01066624cbc
Just to pinpoint the issue, what version of CMake and (if it applies) QtCreator are you using? Cmake 3.10 is required.

It is cmake 3.10.2 on Ubuntu 18.04. Qt & Creator is the latest download with 5.14.2. I called it
cmake -DCMAKE_INSTALL_PREFIX=~/work/liri ..
in subfolder build
Still the same error, now with
cmake -DCMAKE_INSTALL_PREFIX=~/work/liri -DFLUID_USE_SYSTEM_LCS:BOOL=OFF ..
🤷♂️
Can't reproduce on my system neither I can reproduce it in the CI. Have to make an Ubuntu 18.04 VM to test this out.

Ubuntu 18.04 has Qt 5.9, how did you get 5.14.2?
As I wrote earlier, I've downloaded it from Qt.io. I had this problem on (I think) an actual Fedora 31, so the two things coming together are maybe a Qt 5.14.2 with a CMake > 3.10 (as there was no warning about that). I can even check if it runs on Manjaro. On the other hand: what could cause this 'incorrect number of arguments'? Should I go all those steps again, beginning from the correct git checkout, checking all versions of all involved programs? Would that help?
@Slesa With commit fee08d610f8b1447de1c3f3fe65f1dbdf7bfa823, the cmake/shared/ submodule was updated and that fixed your issue. This means you are using an old fluid repository version.
Make sure it's up to date:
git pull
git submodule update
Check the status with:
git rev-parse HEAD
git submodule status
Ok, step by step:
git clone https://github.com/lirios/fluid.git fluidup && cd fluidup
git submodule update --init
git log | grep fee08

What is wrong with me? :)
