[CMake] FindMatlab tips?

[Ryan Pavlik]

  The alternative to this hardcoding is, if the find module is broken 
for the "standard" system, fix it and submit a patch (a lot are only 
minimally maintained and most are at least outdated stylewise), or if 
you know your lib is in a weird place on your system, append that 
location to CMAKE_PREFIX_PATH when calling cmake, rather than from the 
build.  For matlab, you might consider using my "ProgramFilesGlob.cmake" 
module to avoid specifying a list of directories that will become 
outdated - see 
http://github.com/rpavlik/wiimote-head-tracker-gui/blob/master/cmake/FindParasolid.cmake 
with one module that uses it here:
