Как распечатать результаты процесса при `make`?

Question

Как напечатать процесс cargo build , а make in brew install?

Makefile

CARGO=RUSTFLAGS='-F warnings' cargo

...

release:
  $(CARGO) build --all  --release
...

Формула

def install 
  # system command
  system "make release"

  # copy files
  libexec.install Dir["*"] 

  # exec links
  bin.install_symlink "#{libexec}/target/install/bin"  
end

Выходы

...
==> make release
# *** need outputs here ***
