explaining header files path in c

Question

I have a headerpath in ac program that reads

#include <lib/a.h>
#include <lib/b.h>

How do I specify where 'lib' should be in my makefile? It gives me a compile error saying lib/ah is not found. But I know the system path where ah is located. How do I tell my Makefile where to go find lib?

Thanks, Vik.

将参数-I/path/to/include到编译标志（例如CFLAGS或CXXFLAGS ），在该编译标志中，路径指向lib目录的父目录。
