$0 [ --enable-lcov || --disable-tests ] [ --disable-mining ] [ --enable-proton ] [ --enable-compress ] [ --enable-debug ] [ --enable-pvs ] [ MAKEARGS... ]
  Build Pastel and most of its transitive dependencies from
  source. MAKEARGS are applied to both dependencies and Pastel itself.

  If --enable-lcov is passed, Pastel is configured to add coverage
  instrumentation, thus enabling "make cov" to work.
  If --disable-tests is passed instead, the Pastel tests are not built.

  If --disable-mining is passed, Pastel is configured to not build any mining
  code. It must be passed after the test arguments, if present.

  If --enable-proton is passed, Pastel is configured to build the Apache Qpid Proton
  library required for AMQP support. This library is not built by default.

  if --enable-compress is passed, Pastel is configured to compress ticket data with
  zstd library. This is enabled by default.

  if --enable-debug is passed, Pastel will be built with the debug options

  if --enable-pvs is passed, PVS Studio static code analyzer will be used
