# There are a variety of advanced options to configure and build this wrapper, but
# for the simple case of single plugin in a single clap, here are some relevant
# cmake-time options which this wrapper will use. See the documentation for a more
# complete description
#
# CLAP_SDK_ROOT The location of the clap library. Defaults to ../clap
# VST3_SDK_ROOT The location of the VST3 sdk. Defaults tp ../vst3sdk
#
# CLAP_WRAPPER_OUTPUT_NAME   The name of the resulting .vst3 or .component
# CLAP_SUPPORTS_ALL_NOTE_EXPRESSIONS  The wrapper will forward all VST3 note expressions to your CLAP
# CLAP_VST3_TUID_STRING  The VST3 component ::iid as a string; absent this wrapper hashes clap id
# CLAP_WRAPPER_BUNDLE_IDENTIFIER the macOS Bundle Identifier. Absent this it is 'org.cleveraudio.wrapper.(name)'
# CLAP_WRAPPER_BUNDLE_VERSION the macOS Bundle Version. Defaults to 1.0
# CLAP_WRAPPER_WINDOWS_SINGLE_FILE if set to TRUE (default) the windows .vst3 is a single file; false a 3.7 spec folder
# CLAP_WRAPPER_DOWNLOAD_DEPENDENCIES if set will download the needed SDKs using CPM from github
# CLAP_WRAPPER_COPY_AFTER_BUILD if included mac and lin will copy to ~/... (lin t/k)
