rack.mk

#
# A build file to help using sfizz with the VCV Rack SDK
# ------------------------------------------------------
#
# Usage notes:
#
# 1. In the `dep` subfolder of your plugin folder,
#
#    Check out the sfizz source code as a submodule
#
#        git submodule add https://github.com/sfztools/sfizz.git
#
# 2. At the root of your plugin folder,
#
#    Add the following lines, at the bottom of `Makefile`:
#
#        # Include the sfizz library
#        include dep/sfizz/rack.mk
#        CFLAGS += $(SFIZZ_C_FLAGS)
#        CXXFLAGS += $(SFIZZ_CXX_FLAGS)
#        LDFLAGS += $(SFIZZ_LINK_FLAGS)
#        $(TARGET): $(SFIZZ_TARGET)
#
# 3. In the file `Makefile`,
#
#    Above the line `include dep/sfizz/rack.mk`, some configuration variables
#    may be customized.
#
#        SFIZZ_RACK_PLUGIN_DIR = <the root directory of the Rack plugin>
#        SFIZZ_PKG_CONFIG = <a custom pkg-config command>
#        SFIZZ_USE_SNDFILE = <0 disabled, 1 enabled (default)>
#        SFIZZ_SNDFILE_C_FLAGS = <compiler flags of sndfile for C>
#        SFIZZ_SNDFILE_CXX_FLAGS = <compiler flags of sndfile for C++>
#        SFIZZ_SNDFILE_LINK_FLAGS = <linker flags of sndfile>
