* Determining automatically the MCR version on OSX and Windows
* Distinguishing between MCR and Matlab
* Specific tests for the MCR
* mexext on windows does not work properly: the mexext is hardcoded
* Doc updates for the MCR
Fixes: #16487
Implement a brand new FindMatlab module:
- Add support for versions and components.
- Find Matlab and its version in a more precise and multiplatform way.
- Add API to create a new mex extension with documentation.
- Add API to add matlab unit tests (with or without the unit test framework).
- Find as much as possible based on a single Matlab_ROOT_DIR cache entry
and allow the user to change it to re-find everything.
