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