# Remove the non-plugins, it needs intermediate steps because
# we can only replace and not match inverse. Instead we:
#  1/ replace plugins .la targets by plugins names
#  2/ remove every word which is a .la target (ie. non-plugins)
#  3/ rename every plugin name back into the target name

# Generate a list containing the name and path of every plugin being built
# Format: plugin_name: relative/path/to/plugin$(LIBEXT)
# This allows plugins from SUBDIRS (like Qt) to specify their actual location
# The recipee concatenates records from local plugins and those from SUBDIRS
