It's unusual for a library to not be self-contained. Can you give a link to a problem one? And show the code you are using to use that library?
You shouldn't need the quotes rather than brackets when including a library file. Does the file actually exist inside the library?
I'm struggling with is locating these library files on the net so I can install them
I don't see how changing #include "foo.h" to #include <foo.h> is going to help if you don't actually have foo.h. That's the point that isn't clear.
