title: visual studio 2012 cpp files not linked
body: <p>I have a project, called "vertexbuffertest". The project has more than 60 header files and more than 40 cpp files. Now I want to put several header files with their corresponding cpp files in a directory called "datastucts" , which is within the vertexbuffertest directory.</p>
  
  <p>But by doing this, visual studio does not link the cpp files in the directory called "datastructs" and I can not compile the project.</p>
  
  <p>What is the solution, to the described problem.</p>
