# There are three Qt related USES files with different access to Qt.
#   - qmake: The port requires Qt's qmake to build -- creates the configure target
#            - auto includes qt.mk
#   - qt-dist: The port is a port for a part of Qt5
#            - auto inclues qt.mk
#   - qt.mk  - Dependency handling. USE_QT=foo bar
#
#
# Provide support for qmake-based projects
#
# Feature:		qmake
# Usage:		USES=qmake or USES=qmake:ARGS
#			Must be used along with	'USE_QT*=#'
# Valid ARGS:		norecursive outsource
# ARGS description:
# norecursive		Don't pass -recursive argument to qmake binary
# outsource		Perform an out-of-source build
# no_env		Suppress modification of configure and make environment.
# no_configure		Don't add the configure target -- this is implied by 
#			HAS_CONFIGURE=yes and GNU_CONFIGURE=yes
#
#
# Variables for ports:
# QMAKE_ENV		- Environment passed to qmake.
#			Default: ${CONFIGURE_ENV}
# QMAKE_ARGS		- Arguments passed to qmake.
#			Default: see below
# QMAKE_CONFIGURE_ARGS  - Extra arguments passed to qmake after everything
#                       else, such as "-foo -no-bar". The arguments are usually
#                       set in configure.json. This variable is specific to
#                       qmake from Qt 5.
#                       Default: empty
# QMAKE_SOURCE_PATH	- Path to qmake project files.
#			Default: ${WRKSRC} if out-of-source build is
#			requested, empty otherwise.
#
# User defined variables:
# QMAKE_VERBOSE		- Enable verbose configure output.
