;; 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)
(guix build qt-utils)
,@%cmake-build-system-modules))
