gstreamer-meson.eclass: New eclass required for gstreamer-1.18.0+
Gstreamer switched to meson in 1.16.0 and removed autotools support in 1.18.0, this eclass is an update of gstreamer.eclass. One significant change is that we lost the gstreamer_system_link function. Differences from version 1: - Move to EAPI-7, including moving deps from DEPEND to BDEPEND when appropriate - Port python script to perl, this allows to avoid having to add PYTHON_COMPAT into a python-unrelated eclass - Drop errorneous MULTILIB_USEDEP on virtual/pkgconfig - Fix running tests: defining multilib_src_test, media-libs/gstreamer[test] dep - Fix ebuild emesonargs being ignored - Remove legacy prune_libtool_files - virtualx wrapped for testing Differences from version 2: - Get list of plugins from meson_options.txt instead of hard-coding them, this adds GST_PLUGINS_NOAUTO for ones managed by the ebuild - Fix @AUTHOR order - Sort inherits - remove stray semicolon in test - Add virtx to tests - Remove gstreamer_environment_reset - Put GST_ORG_MODULE conditions into gstreamer_multilib_src_{compile,install} - QA warn when IUSE=orc is defined but the option is absent - Pass gst_debug/examples/nls/tests options only when declared - Use code similar to orc for introspection Closes: https://bugs.gentoo.org/690468 Signed-off-by: Haelwenn (lanodan) Monnier <contact@hacktivis.me> Signed-off-by: Sam James <sam@gentoo.org>

+# GStreamer consuming applications should depend on the specific plugins
+# they need as defined in their source code. Usually you can find that
+# out by grepping the source tree for 'factory_make'. If it uses playbin
+# plugin, consider adding media-plugins/gst-plugins-meta dependency, but
+# also list any packages that provide explicitly requested plugins.
