#
# A build file to help using sfizz with the DISTRHO Plugin Framework (DPF)
# ------------------------------------------------------------------------
#
# Usage notes:
#
# 1. Start with the template DPF project
#
#    (for example https://github.com/SpotlightKid/cookiecutter-dpf-effect)
#
# 2. In the top directory of the DPF project, edit `Makefile`
#
#    Add the following line, after the `all` rule definition:
#
#        include <path-to-sfizz>/dpf.mk
#
#    Add `sfizz-lib` to the `libs` rule definition:
#
#        libs: sfizz-lib
#
#    If you want you can add `sfizz-clean` to the `clean` rule.
#
#        clean: sfizz-clean
#
# 3. In the Makefile of your plugin folder, eg. `plugins/MyPlugin/Makefile`
#
#    Add the following line, after `include ../../dpf/Makefile.plugins.mk`
#
#        include <path-to-sfizz>/dpf.mk
#        BUILD_C_FLAGS += $(SFIZZ_C_FLAGS)
#        BUILD_CXX_FLAGS += $(SFIZZ_CXX_FLAGS)
#        LINK_FLAGS += $(SFIZZ_LINK_FLAGS)
#
# 4. Build using `make` from the top folder.
#
