title: Vim Cmake integration
body: <p>I have a cmake project. I want to do the following easily</p>
  
  <ul>
  <li>search the declaration, definition and references of any variable, function, etc. under the cursor, which may be declared in an external header file whose path is added using INCLUDE_DIRECTORIES in CMakeLists.txt</li>
  <li>rename a variable, function, etc. that is declared in the project</li>
  </ul>
  
  <p>How can I set this up?</p>
