78 # Default pkg_setup function for packages that depends on qt4. If you have to
79 # create ebuilds own pkg_setup in your ebuild, call qt4_pkg_setup in it.
80 # This function uses two global vars from ebuild:
81 # - QT4_BUILT_WITH_USE_CHECK - contains use flags that need to be turned on for
82 # =x11-libs/qt-4*
83 # - QT4_OPTIONAL_BUILT_WITH_USE_CHECK - qt4 flags that provides some
84 # functionality, but can alternatively be disabled in ${CATEGORY}/${PN}
85 # (so qt4 don't have to be recompiled)
86 #
87 # NOTE: Using the above vars is now deprecated in favor of eapi-2 use deps
88 #
89 # flags to watch for for Qt4.4:
90 # zlib png | opengl dbus qt3support | sqlite3 ssl
