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