How to compile using Legacy Code and gsl library

I have gsl library and suscesfully compiled the bessel example using MinGW and msys.
However, when I try to use a C-program that needs the gsl library, the mex compiler seems not to recognize the link.
This is what I am trying to run:
def = legacy_code('initialize'); %Inicialize the definitions
def.SFunctionName = 'new_7'; % Define the name of the S-function
def.OutputFcnSpec = 'eemd_v2(double u1[1], double y1[9][400])'; %Specify outputs
def.HeaderFiles = {'eemd.h'}; %Add libraries
def.SourceFiles = {'eemd.c', 'eemd_v2.c'}; %Add the source file
def.IncPaths = {'gsl'}; %Including the folder gsl in the paths
def.LibPaths = {'C:\MinGW\lib', 'C:\MinGW\include', 'C:\MinGW\include\gsl'};
%Generate and compile your function
legacy_code('sfcn_cmex_generate',def)
legacy_code('compile',def)
The legacy generate the new7.c file but when it tries to compilate, this error message is retrived:

I don't know why this is happen because when I try to run the program in the msys it runs normally. I tried to add the options to the compiler but with no sucess:
OPTIONS = {'-I"C:\MinGW\include" -L"C:\MinGW\lib" -lgslcblas -lgsl -lm'};
legacy_code('compile',def,OPTIONS)
My compiler is the 'MinGW64 Compiler (C)'.
What I should do to link the gsl with the MinGW64 Compiler (C) in Matlab?
Thanks
