# Some comment on the prerequisite handling for gb_ComponentTarget__command:
# The whole setup feels - once again - much more complicated then it should be; for an IMHO simple task.
# We can't just add all the $(call gb_ComponentTarget_get_target,%).* target commands to gb_ComponentTarget__command,
# because $(shell cat $(1).filtered) is then evaluated too early, cat'ing a non-existing file.
# Same happens if you add them to a gb_ComponentTarget__pre_command, run before the gb_ComponentTarget__command.
# The various other "macros" add new rules to "expand" the pattern rules with normal rules and prerequisites.
# As a result, the files from the pattern rules aren't cleaned up automagically, which I consider a plus point.
# So the intermediate files must be explicitly added to $(call gb_ComponentTarget_get_clean_target,%).
# In the DISABLE_DYNLOADING case we don't need any COMPONENTPREFIX, we
# put just the static library filename into the uri parameter. For
# each statically linked app using some subset of LO components, there
# is a mapping from library filenames to direct pointers to the
# corresponding PREFIX_component_getFactory functions.
