Problem with installing MPsolve for Matlab

[mahradsv]

I am using MacBook Pro and after entering "./configure" on terminal, I receive the following summary:
MPSolve configuration:

    Source location:	.
Pthread CFLAGS:		-D_THREAD_SAFE 
    C compiler:		gcc
CFLAGS:			-D_REENTRANT -Wall -DMPS_USE_BUILTIN_COMPLEX  -DNICE_DEBUG -fno-math-errno -fomit-frame-pointer -D_MPS_PRIVATE
    LDFLAGS:                 -L/usr/local/opt/gmp/lib -lgmp 
Additional CFLAGS:	-I/usr/local/opt/gmp/ -g -O2
    Debug enabled:		yes
    Check enabled:		no
Octave module:		no
MATLAB (tm) module:	yes (generates examples/matlab/mpsolve-toolbox.tar.gz)
Graphical UI:		no
Python module:          yes

Type 'make' to compile MPSolve, and then make install
to install the binaries, the library and the headers
system-wide.

As you can see I have: MATLAB (tm) module: yes
But then we I enter "make" in the terminal I receive the following error regarding gmp.h file.

Making all in matlab
clang: warning: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated [-Wdeprecated]

Make sure to specify the CFLAGS for gmp using GMP_CFLAGS, for instance

./configure GMP_CFLAGS="-I/usr/local/opt/gmp/"

Other CFLAGS are not passed to the MATLAB compiler because it tends to be picky about what it supports. If this does not work (or you did it already), there may be a problem in how the variables are passed to that script, but I cannot reproduced it locally.

Thanks for your response. I have already tried

./configure GMP_CFLAGS="-I/usr/local/opt/gmp/"

and it did not work. Is there any instruction I can follow to see how the variables are passed to the script?
