Hi,  
If we want to search for library files and include files, we can use  
dir\_config(‘foo’) in a ruby file extconf.rb, and run it with  
./extconf.rb  
–with-foo-dir=/usr/local/foo.  
But what if my include files are not under foo/include or my libraries  
are  
not under foo/lib?  
E.g. my include files are located at foo/inc and my libraries are  
located at  
foo/library.
