title: Haskell Stack build specific executable
body: <p>How to build an specific stack executable file, ie. those specified in <code>projectname.cabal</code>, like:</p>
  
  <pre><code>executable executable-name
    hs-source-dirs:      tools
    main-is:             ExecutableModule.hs
    ghc-options:         -Wall -threaded -rtsopts -with-rtsopts=-N
    build-depends:       base
                       , hsass
                       , hlibsass
  </code></pre>
  
  <p>I would need to compile <code>executable-name</code> and no other. It would be something like:</p>
  
  <pre><code>stack build --executable executable-name
  </code></pre>
