From fb9bbb6f1fbb4e6232221a851f55ca2dc43b012c Mon Sep 17 00:00:00 2001

Subject: [PATCH] Introduce KIO_NO_PUBLIC_QTCONCURRENT option

If set, move Qt5Concurrent to private link interface, drop from
KF5KIOConfig.cmake.in. Originally added in 2f83dde2, but only used
in the implementation, not the API.

Test-built various revdeps successfully against the patched KIO
with/without Qt5Concurrent installed, fixing implicit deps while
at it. KDE Gear packages fixed in >=21.04.2, Plasma in >=5.21.5.
