matlab_add_mex is not found

Hi,

I have installed matlab and matlab-support in ubuntu 14.04 and cmake does not work. Seems like it is not able to find matlab_add_mex in my CMakeList.txt. It's weird because it worked in ubuntu 16.04. I'm using R2016b and cmake version is 2.8. Does anyone know what's wrong?

>> cmake..

-- Configuring MEX files

CMake Error at CMakeLists.txt:17 (matlab_add_mex):

Unknown CMake command "matlab_add_mex".

-- Configuring incomplete, errors occurred!

Ubuntu 16.04 uses version 3.x for CMake which supports 'matlab_add_mex' function which is there inside FindMatlab package. It is not there in CMake version 2.8 which you have by default on Ubuntu 14.04. I expect that upgrading to CMake version 3.3.2 or higher should resolve the error.

Below is the link that might be useful for you to upgrade CMake to a higher version:

This link uses wget http://www.cmake.org/files/v3.2/cmake-3.2.2.tar.gz instead of which you can get 3.3.2 using

wget https://cmake.org/files/v3.3/cmake-3.3.2.tar.gz

Hope this helps.
