g++ header search path

How can I add a folder and ALL ITS SUBFOLDERS to the "include searching path"? Then if myheader.h is in one of these folders, I can use "include <myheader.h>" instead of "include "path/myheader.h" ". I tried g++ -I, but with it I can only specify one folder, I don't know how to make it include all the subfolders.

I am using a library called spuc. And in its source code, it uses "include <XXX.h>" to include the header files from the library, and these header files are in different subfolders of the library root directory. How should I deal with it?

The normal convention is to use
#include <path/myheader.h>

It works well enough for say
#include <sys/stat.h>
for example.

Or you could use a bit of shell script to find all the directories, and make a ridiculously long set of -I parameters out of it.

Thank you! Is there any easy way to add all the sub folders of a folder to the searching path? Because it seems that the source code in that library doesn't follow the normal convention.

This is crude

extra_paths=$(find . -type d | sed 's/^/-I/g')

Then you have
gcc $extra_paths file.c

OK, thank you very much!
