  def install
    mkdir 'macbuild' do
      # CMake finds boost, but variables like this were set in the last
      # version of this formula. Now using the variables listed here:
      #   http://liblas.org/compilation.html
      ENV['Boost_INCLUDE_DIR'] = "#{HOMEBREW_PREFIX}/include"
      ENV['Boost_LIBRARY_DIRS'] = "#{HOMEBREW_PREFIX}/lib"
      system "cmake #{std_cmake_parameters} .."
      system "make"
      system "make test" if ARGV.include? '--with-test'
      system "make install"
    end
  end
