Add some help for fedora installation (from Fedora40 plasma)

[rloutrel]

Description

Add information for Fedora users: since no official client package is provided, a lot will have to go through those steps.

I am still facing issues at the compiling step, but at least dependencies are installed. I will update once compile/install is working.

About the remaining issues:

$ cmake --build build -j$(nproc)
gmake: Makefile: No such file or directory
gmake: *** No rule to make target 'Makefile'.  Stop.

Any clues? I am a bit lost. I understand, that it is something about the makefile and the target is not detected properly, but if some expert could point out where to search, it would really help.

Maybe the configuration step did fail (cmake -S . -B build -D_SOME_ARGS) ? We don't have a "makefile" target ourselves so i think this might be connected to the cmake-generator.
