Hello I have a project with includes files in other folders than my project folder. I need to know how to indicate to Xcode where to search the includes. For exemple I have this in my code #include <glibconfig.h> And I know than this file is located in "/opt/local/include/glib-2.0/glib" How can I set XCode so it will look in this directory to find the glibconfig.h file. Thank to help
