# @DESCRIPTION:
# Default pkg_setup function for packages that depends on qt4. If you have to
# create ebuilds own pkg_setup in your ebuild, call qt4_pkg_setup in it.
# This function uses two global vars from ebuild:
# - QT4_BUILT_WITH_USE_CHECK - contains use flags that need to be turned on for
# =x11-libs/qt-4*
# - QT4_OPTIONAL_BUILT_WITH_USE_CHECK - qt4 flags that provides some
# functionality, but can alternatively be disabled in ${CATEGORY}/${PN}
# (so qt4 don't have to be recompiled)
#
# NOTE: Using the above vars is now deprecated in favor of eapi-2 use deps
#
# flags to watch for for Qt4.4:
# zlib png | opengl dbus qt3support | sqlite3 ssl

# the subdirs template, you should run eqmake4 on the top-level project
# file only, unless you have strong reasons to do things differently.
# During the building, qmake will be automatically re-invoked with the
# right arguments on every directory specified inside the top-level
# project file by the SUBDIRS variable.
