How to put something in my "include path"?

I have all my project include files in a specific dir (called include, in my project dir). When I include them in a cpp file, I need to 

#include "include/somefile.h"

How can I make it so that I can do

#include <somefile.h>

?

Using double quotes to include looks within the local working directory, while includes wrapped in angle brackets tell the linker/compiler to look in standard locations such as /usr/bin/ (on *nix platforms). You can tell it to look other places with the -I compiler directive (with gcc/g++ at least, IDEs like Visual Studio have their own mechanisms).

Use the -I flag of the compiler. Like:

~$ c++ -Wall -Werror -pedantic -I/home/user/include -c source_file.cpp
