title: How to build cmake-project with atom text editor?
body: <p>I've installed packages build and build-make, and it's not obvious what to do next. 
  Build-tools package is bugged and impossible to install now. </p>
  
  <p>I have cmake project, sucsessfully build in different IDE: QTCreator, VisualStudio, via bash. So i want to make it with atom, and there is no instruction how to use it's build-make package. Documentation to this package is empty.</p>
  
  <p>in bash i call: <code>cmake ../src</code> from my build dir. 
  So in <code>.atom-build.json</code> i put this command and point directory as working - and nothing happens, on f9 i've god <code>"Cannot read peoperty "exec" or undefined"</code></p>
