# FindMatlab
# ----------
#
# Finds Matlab installations and provides Matlab tools and libraries to cmake.
#
# This package first intention is to find the libraries associated with Matlab
# in order to be able to build Matlab extensions (mex files). It can also be
# used:
#
# * run specific commands in Matlab
# * declare Matlab unit test
# * retrieve various information from Matlab (mex extensions, versions and
# release queries, ...)
#
# The module supports the following components:
#
# * ``MX_LIBRARY`` and ``ENG_LIBRARY`` respectively the MX and ENG libraries of
# Matlab
# * ``MAIN_PROGRAM`` the Matlab binary program.
#
# .. note::
#
# The version given to the :command:`find_package` directive is the Matlab
# **version**, which should not be confused with the Matlab *release* name
# (eg. `R2014`).
# The :command:`matlab_get_version_from_release_name` and
# :command:`matlab_get_release_name_from_version` allow a mapping
# from the release name to the version.
#
# The variable :variable:`Matlab_ROOT_DIR` may be specified in order to give
# the path of the desired Matlab version. Otherwise, the behaviour is platform
# specific:
#
# * Windows: The installed versions of Matlab are retrieved from the
# Windows registry
# * OS X: The installed versions of Matlab are given by the MATLAB
# paths in ``/Application``. If no such application is found, it falls back
# to the one that might be accessible from the PATH.
# * Unix: The desired Matlab should be accessible from the PATH.
#
# Additional information is provided when :variable:`MATLAB_FIND_DEBUG` is set.
# When a Matlab binary is found automatically and the ``MATLAB_VERSION``
# is not given, the version is queried from Matlab directly.
# On Windows, it can make a window running Matlab appear.
#
# The mapping of the release names and the version of Matlab is performed by
# defining pairs (name, version). The variable
# :variable:`MATLAB_ADDITIONAL_VERSIONS` may be provided before the call to
# the :command:`find_package` in order to handle additional versions.
#
# A Matlab scripts can be added to the set of tests using the
# :command:`matlab_add_unit_test`. By default, the Matlab unit test framework
# will be used (>= 2013a) to run this script, but regular ``.m`` files
# returning an exit code can be used as well (0 indicating a success).
#
# Module Input Variables
# ^^^^^^^^^^^^^^^^^^^^^^
#
# Users or projects may set the following variables to configure the module
# behaviour:
#
# :variable:`Matlab_ROOT_DIR`
# the root of the Matlab installation.
# :variable:`MATLAB_FIND_DEBUG`
# outputs debug information
# :variable:`MATLAB_ADDITIONAL_VERSIONS`
# additional versions of Matlab for the automatic retrieval of the installed
# versions.
#
# Variables defined by the module
# ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
#
# Result variables
# """"""""""""""""
#
# ``Matlab_FOUND``
# ``TRUE`` if the Matlab installation is found, ``FALSE``
# otherwise. All variable below are defined if Matlab is found.
# ``Matlab_ROOT_DIR``
# the final root of the Matlab installation determined by the FindMatlab
# module.
# ``Matlab_MAIN_PROGRAM``
# the Matlab binary program. Available only if the component ``MAIN_PROGRAM``
# is given in the :command:`find_package` directive.
# ``Matlab_INCLUDE_DIRS``
# the path of the Matlab libraries headers
# ``Matlab_MEX_LIBRARY``
# library for mex, always available.
# ``Matlab_MX_LIBRARY``
# mx library of Matlab (arrays). Available only if the component
# ``MX_LIBRARY`` has been requested.
# ``Matlab_ENG_LIBRARY``
# Matlab engine library. Available only if the component ``ENG_LIBRARY``
# is requested.
# ``Matlab_LIBRARIES``
# the whole set of libraries of Matlab
# ``Matlab_MEX_COMPILER``
# the mex compiler of Matlab. Currently not used.
# Available only if the component ``MEX_COMPILER`` is asked
#
# Cached variables
# """"""""""""""""
#
# ``Matlab_MEX_EXTENSION``
# the extension of the mex files for the current platform (given by Matlab).
# ``Matlab_ROOT_DIR``
# the location of the root of the Matlab installation found. If this value
# is changed by the user, the result variables are recomputed.
#
# Provided macros
# ^^^^^^^^^^^^^^^
#
# :command:`matlab_get_version_from_release_name`
# returns the version from the release name
# :command:`matlab_get_release_name_from_version`
# returns the release name from the Matlab version
#
# Provided functions
# ^^^^^^^^^^^^^^^^^^
#
# :command:`matlab_add_mex`
# adds a target compiling a MEX file.
# :command:`matlab_add_unit_test`
# adds a Matlab unit test file as a test to the project.
# :command:`matlab_extract_all_installed_versions_from_registry`
# parses the registry for all Matlab versions. Available on Windows only.
# The part of the registry parsed is dependent on the host processor
# :command:`matlab_get_all_valid_matlab_roots_from_registry`
# returns all the possible Matlab paths, according to a previously
# given list. Only the existing/accessible paths are kept. This is mainly
# useful for the searching all possible Matlab installation.
# :command:`matlab_get_mex_suffix`
# returns the suffix to be used for the mex files
# (platform/architecture dependent)
# :command:`matlab_get_version_from_matlab_run`
# returns the version of Matlab, given the full directory of the Matlab
# program.
#
#
# Known issues
# ^^^^^^^^^^^^
#
# **Symbol clash in a MEX target**
# By default, every symbols inside a MEX
# file defined with the command :command:`matlab_add_mex` have hidden
# visibility, except for the entry point. This is the default behaviour of
# the MEX compiler, which lowers the risk of symbol collision between the
# libraries shipped with Matlab, and the libraries to which the MEX file is
# linking to. This is also the default on Windows platforms.
#
# However, this is not sufficient in certain case, where for instance your
# MEX file is linking against libraries that are already loaded by Matlab,
# even if those libraries have different SONAMES.
# A possible solution is to hide the symbols of the libraries to which the
# MEX target is linking to. This can be achieved in GNU GCC compilers with
# the linker option ``-Wl,--exclude-libs,ALL``.
#
# **Tests using GPU resources**
# in case your MEX file is using the GPU and
# in order to be able to run unit tests on this MEX file, the GPU resources
# should be properly released by Matlab. A possible solution is to make
# Matlab aware of the use of the GPU resources in the session, which can be
# performed by a command such as ``D = gpuDevice()`` at the beginning of
# the test script (or via a fixture).
#
#
# Reference
# ^^^^^^^^^
#
# .. variable:: Matlab_ROOT_DIR
#
# The root folder of the Matlab installation. If set before the call to
# :command:`find_package`, the module will look for the components in that
# path. If not set, then an automatic search of Matlab
# will be performed. If set, it should point to a valid version of Matlab.
#
# .. variable:: MATLAB_FIND_DEBUG
#
# If set, the lookup of Matlab and the intermediate configuration steps are
# outputted to the console.
#
# .. variable:: MATLAB_ADDITIONAL_VERSIONS
#
# If set, specifies additional versions of Matlab that may be looked for.
# The variable should be a list of strings, organised by pairs of release
# name and versions, such as follows::
#
# set(MATLAB_ADDITIONAL_VERSIONS
# "release_name1=corresponding_version1"
# "release_name2=corresponding_version2"
# ...
# )
#
# Example::
#
# set(MATLAB_ADDITIONAL_VERSIONS
# "R2013b=8.2"
# "R2013a=8.1"
# "R2012b=8.0")
#
# The order of entries in this list matters when several versions of
# Matlab are installed. The priority is set according to the ordering in
# this list.
