# - this module looks for Matlab
# 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_MAT_LIBRARY:  path to libmat.lib # added
#  MATLAB_ENG_LIBRARY: path to libeng.lib
#  MATLAB_ROOT: path to Matlab's root directory

# This is a derivative work of file FindMatlab.cmake released with
# CMake v2.8, because the original seems to be a bit outdated and
# doesn't work with my Windows XP and Visual Studio 10 install
#
# (Note that the original file does work for Ubuntu Natty)
