[CMake] FindMatlab tips?

[Brian Davis]

I think Ryan's comments help support my assessment of FindWhatevers.  Add
recently downloaded GTK in GLade 3.6 for windows and can now add this to
list of not working FindWhatevers.  find_package( GTK2 ) of course does not
work for this as of today.

Statements like

"CAUTION: The contents of this page may be obsolete"
and
"The information in the How to write a FindFoo.cmake module section is
somewhat dated. "

at http://www.cmake.org/Wiki/CMake:How_To_Find_Installed_Software regarding
how to write a FindWhatever probably are not helping would be developers.

You might find this interesting regarding PATHS and HINTS  of
find_package(cuda) :

2. Search paths specified in cmake-specific environment variables. These are
intended to be set in the user's shell configuration. This can be skipped if
NO_CMAKE_ENVIRONMENT_PATH is passed.

   CMAKE_PREFIX_PATH
   CMAKE_FRAMEWORK_PATH
   CMAKE_APPBUNDLE_PATH

3. Search paths specified by the HINTS option. These should be paths
computed by system introspection, such as a hint provided by the location of
another item already found. Hard-coded guesses should be specified with the
PATHS option.

7. Search cmake variables defined in the Platform files for the current
system. This can be skipped if NO_CMAKE_SYSTEM_PATH is passed.
CMAKE_SYSTEM_PREFIX_PATH
CMAKE_SYSTEM_FRAMEWORK_PATH
CMAKE_SYSTEM_APPBUNDLE_PATH

8. Search paths specified by the PATHS option. These are typically
hard-coded guesses.

If you try CMAKE_PREFIX_PATH post back if it worked/did not work as I have
not tried it.  I finally got smart... and gave up tying to get it to work.
