Usage:

$0 --help
  Show this help message and exit.

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

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

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

  If --disable-rust is passed, Hush is configured to not build any Rust language
  assets. It must be passed after test/mining arguments, if present.

  If --enable-proton is passed, Hush is configured to build the Apache Qpid Proton

  library required for AMQP support. This library is not built by default.
  It must be passed after the test/mining/Rust arguments, if present.

  If --disable-libs is passed, Zcash is configured to not build any libraries like
  'libzcashconsensus'.
