mex compile cannot find path to C/C++ Libraries - Example: lcc preprocessor error: .\class_handle.hpp:4 SysSimChan​nelInterfa​ce.cpp:2 Could not find include file stdint.h

I'm trying to compile a mex file using the Matlab C/C++ compiler. I understood that C/C++ std libraries are automatically included, but I get these error messages:

lcc preprocessor error: .\class_handle.hpp:4 SysSimChannelInterface.cpp:2 Could not find include file stdint.h

lcc preprocessor error: .\class_handle.hpp:5 SysSimChannelInterface.cpp:2 Could not find include file string

This is actually not from my code, but from an hpp file I downloaded from Matlab Central (by Oliver Wood). (See "Making C++ objects persistent between mex".) The hpp file is included in the cpp file that I'm trying to compile with the mex command in Matlab.

It appears that the compiler doesn't know where the libraries are. I tried setting a Matlab path to the VC++ location, and that didn't help.

LCC is a C-compiler, which cannot compile C++ code.

When you have MSVC installed, use this for compilations.
