Writing a .mat from C++ - Can't use MATLAB Data API with C Matrix API

Hi, i'm trying to use the MATLAB Data API from C++ using the Data API. Writing mex files isn't an issue, however i'm also trying to deploy parts of my application to a standalone executable to generate a .mat file. I'm compiling with Visual Studio 2017 and when i include mat.h, i get the error "Using MATLAB Data API with C Matrix API is not supported."

Is there a Data API compatible version of the Mat-File API library?
