Icons installed by apps

[Jaroslaw Staniek]

Dear All,
One more question about the theme setting behaviour or philosophy. In
a Plasma4 session I am using a custom prefix for KF5 libs and
KF5-based apps.

Then in $XDG_CONFIG_HOME/.config5/kdeglobals editing setting

[Icons]
Theme=....

does not seem to mean anything to these apps.

Also having all the XDG_* variables set, while using systemsettings
(from Plasma4, I am testing support for non-Plasma5 environments) to
alter the icon theme I naively thought the kdeglobals file would be.
No, the host's "Plasma4's system" kdeglobals is altered instead.

Why this behaviour? Is there any way to change icon theme in a local
PREFIX I use for KF5 software without altering the host's theme and
without using Plasma5 sessions?
