"gsl/gsl_rng.h' file not found" after OSX El Capitan upgrade

I just updated to the newest OSX, El Capitan, and I am having problems with compiling a C program. It compiled fine just before the upgrade of the OS. After it I got a warning message already for my LaTeX text editor, Latexian:

Latexian message

But since I don't use preview or compilation inside the program and compile in the terminal with "latex file.tex" it works fine.

Now my problem is with my .c program which includes one of the GSL libraries, here is my header:

#include <math.h>
#include <stdio.h>
#include <stdlib.h>
#include <gsl/gsl_rng.h>
#include <gsl/gsl_randist.h>

When compiling I get the following:

performance.c:4:10: fatal error: 'gsl/gsl_rng.h' file not found
#include <gsl/gsl_rng.h>
          ^
1 error generated.

I am guessing something changed in the OSX because of these two situations but the latter is a huge problem for me since I'm finishing my thesis! Hope my question is clear, it's my first.

EDIT:

And I'm guessing this is the problem

El Capitan's System Integrity Protection will shift utilities' functions

In my case this line solved this linking error

gcc $(gsl-config --cflags) name_of_file.c $(gsl-config --libs) -o name_of_file

When compiling with GCC you may have to manually specify the parent directory that contains the gsl subfolder. Similarly you will have to specify the directory to find the libraries in as well. The include directory can be added as a search path to gcc with the -I option, and the library search path with -L. In your case that is done by adding this to your GCC compilation:

-I/usr/local/include -L/usr/local/lib
