@end defvr
@defvr {Scheme Variable} qt-build-system
This variable is exported by @code{(guix build-system qt)}. It
is intended for use with applications using Qt or KDE.
This build system adds the phase @code{qt-wrap} to the ones defined by
@var{cmake-build-system}, after the @code{install} phase.
This phase 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.
It is possible to exclude specific package outputs from that wrapping process
by listing their names in the @code{#:qt-wrap-excluded-outputs} parameter.
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.
@end defvr
@defvr {Scheme Variable} r-build-system
This variable is exported by @code{(guix build-system r)}. It
implements the build procedure used by @uref{https://r-project.org, R}

;; Commentary:
;;
;; This build system is an extension of the 'cmake-build-system'. It
;; accommodates the needs of Qt and KDE applications by adding a phase run
;; after the 'install' phase:
;;
;; 'qt-wrap' phase:
;;
;; This phase looks for Qt5 plugin paths, QML paths and some XDG paths as well
;; as the corresponding environment variables. If any of these is found in
;; the output or if respective environment variables are set, then all
;; programs in the output's "bin", "sbin", "libexec and "lib/libexec"
;; directories are wrapped in scripts defining the necessary environment
;; variables.
;;
;; Code:
(define %qt-build-system-modules
;; Build-side modules imported and used by default.
`((guix build qt-build-system)
