# - This module looks for Matlab and associated development libraries
# Defines:
#  MATLAB_INCLUDE_DIR: include path for mex.h, engine.h
#  MATLAB_LIBRARIES:        required libraries: libmex, etc
#  MATLAB_MEX_LIBRARY:      path to libmex.lib
#  MATLAB_MX_LIBRARY:       path to libmx.lib
#  MATLAB_ENG_LIBRARY:      path to libeng.lib
#  MATLAB_MEX_VERSION_FILE: path to mexversion.rc or mexversion.c
#  MATLAB_MEX_SUFFIX:       filename suffix for mex-files (e.g. '.mexglx' or '.mexw64')
