How can I make my makefile also look for the c++11 directory?

I compiled my program and when I upload it to be marked with fitch fork I get a few errors. The program compiles and runs when I run it outside fitch fork, I think the main problem is that my make file is not calling c++11 libraries.

Error Message:

make_clean 2

rm: cannot remove '*.o': No such file or directory rm: cannot remove 'main': No such file or directory make: *** [makefile:14: clean] Error 1
