annotate Makefile @ 59:fa79c4ec847d host-factory-stuff

* Put hostext stuff in the HostExt sub-namespace
* Tidy up system-specific stuff in PluginLoader
* Make PluginLoader return a deletion-notifying wrapper which permits the
  library to be unloaded when no longer in use
* Add PluginChannelAdapter
* Make vamp-simple-host use PluginChannelAdapter, and use the PluginLoader
  for plugin-running task.  Also some other enhancements to host

# Makefile for the Vamp plugin SDK.  This builds the SDK objects,
# libraries, example plugins, and the test host.  Please adjust to
# suit your operating system requirements.

# Default build target (or use "make <target>" to select one).
# Targets are:
#   all       -- build everything
#   sdk       -- build all the Vamp SDK libraries for plugins and hosts
#   plugins   -- build the example plugins (and the SDK if required)
#   host      -- build the simple Vamp plugin host (and the SDK if required)
#   test      -- build the host and example plugins, and run a quick test
#   clean     -- remove binary targets
#   distclean -- remove all targets
#
