# 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
#
#
# Variables for ports:
# QMAKE_ENV		- Environment passed to qmake.
#			Default: ${CONFIGURE_ENV}
# QMAKE_ARGS		- Arguments passed to qmake.
#			Default: see below
# 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.
