title: make from within vim
body: <p>I am using gvim for coding c++. Since my program involves cmake, my sources are located in a different directory than my build.</p>
  
  <p>How can I still invoke :make from within vim so that the correct make file within the build directory is found?</p>
  
  <p>how can I then subsequently start my application with the very same command line style and one keystroke?</p>
