find matlab

CMake/findMatlab.cmake

+# - Try to find a version of Matlab and headers/library required by the 
+#   used compiler. It determines the right MEX-File extension and add 
+#   a macro to help the build of MEX-functions.
+#
+# This module detects a Matlab's version between Matlab 7.0
+# and Matlab 7.9
+#
+# This module defines: 
+#  MATLAB_ROOT: Matlab installation path
+#  MATLAB_INCLUDE_DIR: include path for mex.h, engine.h
+#  MATLAB_MEX_LIBRARY: path to libmex.lib
+#  MATLAB_MX_LIBRARY:  path to libmx.lib
+#  MATLAB_ENG_LIBRARY: path to libeng.lib
+#  MATLAB_LIBRARIES:   required libraries: libmex, libmx, libeng
+#  MEX_EXTENSION: MEX extension required for the current plateform
+#  MATLAB_CREATE_MEX: macro to build a MEX-file
+#
+# The macro MATLAB_CREATE_MEX requires in this order:
+#  - function's name which will be called in Matlab;
+#  - C/C++ source files;
+#  - third libraries required.
