title: Eclipse C/C++ (CDT) import files into project - header file not found - include path
body: <p>I am trying to import files into an Eclipse C project and compile it.  The build process cannot find the local header files.  The header files are located in the src directory. How can I edit the include path in eclipse?  If I were doing it manually I could specify the -I option in gcc.</p>
