title: Is it possible to set preprocessor macro in sln file and not in a project? (VS2008 c++)
body: <p>I am maintaining a large codebase and some vcproj files are used in different solutions.  Due to some horrendous configuration and dependencies it seems the best way to handle some build issues is to #ifdef the code but in order to do that I need to set a preprocessor definition at the solution file level and not at the vcproj level.</p>
  
  <p>Is that possible?</p>
  
  <p>How to do it?</p>
