Options:
-dyn-manifest: use dynamic manifests (requires LV2 host support)
-gui: build the plugin GUI (requires LV2 UI host support)
-httpd: activate HTTP control (add -qrcode to activate QR code generation)
-keep: retain the build directory
-nometa: ignore metadata (author information etc.) from the Faust source
-nomidicc: plugin doesn't process MIDI control data
-notuning: disable the tuning control (instruments only)
-novoicectrls: no extra polyphony/tuning controls on GUI (instruments only)
-nvoices N: number of synth voices (instruments only; arg must be an integer)
-osc: activate OSC control
-qt4, -qt5: select the GUI toolkit (requires Qt4/5; implies -gui)
-style S: select the stylesheet (arg must be Default, Blue, Grey or Salmon)
-uri-prefix URI: URI prefix of plugin (arg must be a valid URI)

Environment variables:
FAUSTINC: specify the location of the Faust include directory
  Default: $FAUSTINC
FAUSTLIB: specify the location of the Faust LV2 library files
  Default: $FAUSTLIB
QMAKE: specify the location of the qmake binary of the desired Qt version
  Default: $QMAKE
