dnl GST_*:              flags shared by built objects to link against GStreamer
dnl GST_ALL_LDFLAGS:    linker flags shared by all
dnl GST_LIB_LDFLAGS:    additional linker flags for all libaries
dnl GST_LT_LDFLAGS:     library versioning of our libraries
dnl GST_PLUGIN_LDFLAGS: flags to be used for all plugins

dnl prefer internal headers to already installed ones
dnl also add builddir include for enumtypes and marshal
dnl add GST_OPTION_CFLAGS, but overridable

GST_CXXFLAGS="$GST_CXXFLAGS \$(GST_OPTION_CXXFLAGS)"
AC_SUBST(GST_CFLAGS)
