This build system adds the phase @code{qt-wrap} to the ones defined by

This build system adds the following two phases to the ones defined by
@code{cmake-build-system}:
This phase searches for Qt5 plugin paths, QML paths and some XDG in the inputs
@table @code
@item check-setup
The phase @code{check-setup} prepares the environment for running
the checks as commonly used by Qt test programs.
For now this only sets some environment variables:
@code{QT_QPA_PLATFORM=offscreen},
@code{DBUS_FATAL_WARNINGS=0} and
@code{CTEST_OUTPUT_ON_FAILURE=1}.
This phase is added before the @code{check} phase.
It's a separate phase to ease adjusting if necessary.
@item qt-wrap
The phase @code{qt-wrap}
searches for Qt5 plugin paths, QML paths and some XDG in the inputs
and output. In case some path is found, all programs in the output's
@file{bin/}, @file{sbin/}, @file{libexec/} and @file{lib/libexec/} directories
are wrapped in scripts defining the necessary environment variables.

This is useful when an output is known not to contain any Qt binaries, and
where wrapping would gratuitously add a dependency of that output on Qt, KDE,
or such.
This phase is added after the @code{install} phase.
