title: Can I share source code among projects in Eclipse (CDT) without using absolute paths?
body: <p>I know there are similar questions with answers, and some of them are being offered to my as I type this. However, none of them seem to offer a solution without absolute paths. </p>
  
  <p>I have two projects in an SVN project, and they need use some .cpp and .h files in a shared way. I simply could not find a way of avoiding absolute paths, which are directly related to the directory I check out my code. 
  It is very likely that everyone trying to use the code will have to modify these variables first. </p>
  
  <p>I could not see any solution without using a variable (at best). Are there any recent tricks/developments I'm missing?</p>
