@mlaurent Why the switch to the old unprefixed (and deprecated) variable here?

[Laurent Montel]

Oops indeed I made an error I read "SYSTEMDUSERUNITDIR Systemd User Units (lib/systemd/user) [SYSTEMD_USER_UNIT_INSTALL_DIR]. Since 5.65 " for me it was the last version of variable.

Perhaps we need to make it as deprecated.

[Friedrich W. H. Kossebau]

I would not know a way to mark cmake variables as deprecated, so putting things into the docs is all we might be able to. Currently there is a general comment at the top of the list of vars in the docs, saying

default values in parentheses and alternative, deprecated variable name in square brackets)

Repeating a "deprecated:" text in all places might be too much noise, also will blow up the layout in some places.

Any ideas how to improve things surely welcome.

[Friedrich W. H. Kossebau]

Though it is strange that at 5.65, when the unprefixed ones were already deprecated, this new one was added. No idea why, in any case, gone in KDEInstallDirs6.
