VS: Add version year to generator names

Rename the Visual Studio >= 10 generators to indicate the version year: Visual Studio 10 => Visual Studio 10 2010 Visual Studio 11 => Visual Studio 11 2012 Visual Studio 12 => Visual Stduio 12 2013 Report the names with the year to the list of available generators so that the cmake-gui drop-down shows the years. When selecting a generator from the "-G" option or from an existing CMAKE_GENERATOR cache entry, recognize names without the years for compatibility and map them to the names with years. Update the generator names in the cmake-generators.7 manual.

See accompanying # file Copyright.txt or https://cmake.org/licensing for details. #[=======================================================================[.rst: FindMatlab ---------- Finds Matlab or Matlab Compiler Runtime (MCR) and provides Matlab tools, libraries and compilers to CMake. This package primary purpose is to find the libraries associated with Matlab or the MCR in order to be able to build Matlab extensions (mex files). It can also be used: * to run specific commands in Matlab in case Matlab is available * for declaring Matlab unit test * to retrieve various information from Matlab (mex extensions, versions and release queries, ...) The module supports the following components: * ``ENG_LIBRARY`` and ``MAT_LIBRARY``: respectively the ``ENG`` and ``MAT`` libraries of Matlab * ``MAIN_PROGRAM`` the Matlab binary program. Note that this component is not available on the MCR version, and will yield an error if the MCR is found instead of the regular Matlab installation. * ``MEX_COMPILER`` the MEX compiler. * ``MCC_COMPILER`` the MCC compiler, included with the Matlab Compiler add-on. * ``SIMULINK`` the Simulink environment. .. 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` provide a mapping between the release name and 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/MCR are retrieved from the Windows registry * OS X: The installed versions of Matlab/MCR are given by the MATLAB default installation 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``. This does not work for MCR installation and :variable:`Matlab_ROOT_DIR` should be specified on this platform. Additional information is provided when :variable:`MATLAB_FIND_DEBUG` is set. When a Matlab/MCR installation is found automatically and the ``MATLAB_VERSION`` is not given, the version is queried from Matlab directly (on Windows this may pop up a Matlab window) or from the MCR installation. 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), always available. ``Matlab_ENG_LIBRARY`` Matlab engine library. Available only if the component ``ENG_LIBRARY`` is requested. ``Matlab_MAT_LIBRARY`` Matlab matrix library. Available only if the component ``MAT_LIBRARY`` is requested. ``Matlab_ENGINE_LIBRARY`` Matlab C++ engine library, always available for R2018a and newer. ``Matlab_DATAARRAY_LIBRARY`` Matlab C++ data array library, always available for R2018a and newer. ``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 requested. ``Matlab_MCC_COMPILER`` the mcc compiler of Matlab. Included with the Matlab Compiler add-on. Available only if the component ``MCC_COMPILER`` is requested. 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 or MCR 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/MCR, given the full directory of the Matlab/MCR installation path. 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 target links to ``libmex`` and ``libmx`` by default. ``OUTPUT_NAME`` if given, overrides the default name. The default name is the name of the target without any prefix and with ``Matlab_MEX_EXTENSION`` suffix. ``DOCUMENTATION`` if given, the file ``file.txt`` will be considered as being the documentation file for the MEX file. This file is copied into the same folder without any processing, with the same name as the final mex file, and with extension `.m`. In that case, typing ``help <name>`` in Matlab prints the documentation contained in this file. ``R2017b`` or ``R2018a`` may be given to specify the version of the C API to use: ``R2017b`` specifies the traditional (separate complex) C API, and corresponds to the ``-R2017b`` flag for the `mex` command. ``R2018a`` specifies the new interleaved complex C API, and corresponds to the ``-R2018a`` flag for the `mex` command. Ignored if MATLAB version prior to R2018a. Defaults to ``R2017b``. ``MODULE`` or ``SHARED`` may be given to specify the type of library to be created. ``EXECUTABLE`` may be given to create an executable instead of a library. If no type is given explicitly, the type is ``SHARED``. The documentation file is not processed and should be in the following format: :: % This is the documentation function ret = mex_target_output_name(input1) #]=======================================================================] function(matlab_add_mex) if(NOT WIN32) # we do not need all this on Windows # pthread options if(CMAKE_CXX_COMPILER_LOADED) check_cxx_compiler_flag(-pthread HAS_MINUS_PTHREAD) elseif(CMAKE_C_COMPILER_LOADED) check_c_compiler_flag(-pthread HAS_MINUS_PTHREAD) endif() # we should use try_compile instead, the link flags are discarded from # this compiler_flag function. #check_cxx_compiler_flag(-Wl,--exclude-libs,ALL HAS_SYMBOL_HIDING_CAPABILITY) endif() set(options EXECUTABLE MODULE SHARED R2017b R2018a) set(oneValueArgs NAME DOCUMENTATION OUTPUT_NAME) set(multiValueArgs LINK_TO SRC) set(prefix _matlab_addmex_prefix) cmake_parse_arguments(${prefix} "${options}" "${oneValueArgs}" "${multiValueArgs}" ${ARGN} ) if(NOT ${prefix}_NAME) message(FATAL_ERROR "[MATLAB] The MEX target name cannot be empty") endif() if(NOT ${prefix}_OUTPUT_NAME) set(${prefix}_OUTPUT_NAME ${${prefix}_NAME}) endif() if(NOT ${Matlab_VERSION_STRING} VERSION_LESS "9.1") # For 9.1 (R2016b) and newer, add version source file # TODO: check the file extensions in ${${prefix}_SRC} to see if they're C or C++ files # Currently, the C and C++ versions of the version files are identical, so this doesn't matter. set(MEX_VERSION_FILE "${Matlab_ROOT_DIR}/extern/version/c_mexapi_version.c") #set(MEX_VERSION_FILE "${Matlab_ROOT_DIR}/extern/version/cpp_mexapi_version.cpp") endif() if(NOT ${Matlab_VERSION_STRING} VERSION_LESS "9.4") # For 9.4 (R2018a) and newer, add API macro if(${${prefix}_R2018a}) set(MEX_API_MACRO "MATLAB_DEFAULT_RELEASE=R2018a") else() set(MEX_API_MACRO "MATLAB_DEFAULT_RELEASE=R2017b") endif() endif() if(${prefix}_EXECUTABLE) add_executable(${${prefix}_NAME} ${${prefix}_SRC} ${MEX_VERSION_FILE} ${${prefix}_DOCUMENTATION} ${${prefix}_UNPARSED_ARGUMENTS}) else() if(${prefix}_MODULE) set(type MODULE) else() set(type SHARED) endif() add_library(${${prefix}_NAME} ${type} ${${prefix}_SRC} ${MEX_VERSION_FILE} ${${prefix}_DOCUMENTATION} ${${prefix}_UNPARSED_ARGUMENTS}) endif() target_include_directories(${${prefix}_NAME} PRIVATE ${Matlab_INCLUDE_DIRS}) if(Matlab_HAS_CPP_API) target_link_libraries(${${prefix}_NAME} ${Matlab_ENGINE_LIBRARY} ${Matlab_DATAARRAY_LIBRARY}) endif() target_link_libraries(${${prefix}_NAME} ${Matlab_MEX_LIBRARY} ${Matlab_MX_LIBRARY} ${${prefix}_LINK_TO}) set_target_properties(${${prefix}_NAME} PROPERTIES PREFIX "" OUTPUT_NAME ${${prefix}_OUTPUT_NAME} SUFFIX ".${Matlab_MEX_EXTENSION}") target_compile_definitions(${${prefix}_NAME} PRIVATE ${MEX_API_MACRO} MATLAB_MEX_FILE) # documentation if(NOT ${${prefix}_DOCUMENTATION} STREQUAL "") get_target_property(output_name ${${prefix}_NAME} OUTPUT_NAME) add_custom_command( TARGET ${${prefix}_NAME} PRE_BUILD COMMAND ${CMAKE_COMMAND} -E copy_if_different ${${prefix}_DOCUMENTATION} $<TARGET_FILE_DIR:${${prefix}_NAME}>/${output_name}.m COMMENT "[MATLAB] Copy ${${prefix}_NAME} documentation file into the output folder" ) endif() # documentation # entry point in the mex file + taking care of visibility and symbol clashes. if(WIN32) if (MSVC) set(_link_flags "${_link_flags} /EXPORT:mexFunction") if(NOT ${Matlab_VERSION_STRING} VERSION_LESS "9.1") # For 9.1 (R2016b) and newer, export version set(_link_flags "${_link_flags} /EXPORT:mexfilerequiredapiversion") endif() if(Matlab_HAS_CPP_API) set(_link_flags "${_link_flags} /EXPORT:mexCreateMexFunction /EXPORT:mexDestroyMexFunction /EXPORT:mexFunctionAdapter") #TODO: Is this necessary? endif() set_property(TARGET ${${prefix}_NAME} APPEND PROPERTY LINK_FLAGS ${_link_flags}) endif() # TODO: what if there's a different compiler on Windows? set_target_properties(${${prefix}_NAME} PROPERTIES DEFINE_SYMBOL "DLL_EXPORT_SYM=__declspec(dllexport)") else() if(${Matlab_VERSION_STRING} VERSION_LESS "9.1") # For versions prior to 9.1 (R2016b) set(_ver_map_files ${Matlab_EXTERN_LIBRARY_DIR}/mexFunction.map) else() # For 9.1 (R2016b) and newer set(_ver_map_files ${Matlab_EXTERN_LIBRARY_DIR}/c_exportsmexfileversion.map) endif() if(NOT ${Matlab_VERSION_STRING} VERSION_LESS "9.5") # For 9.5 (R2018b) (and newer?) target_compile_options(${${prefix}_NAME} PRIVATE "-fvisibility=default") # This one is weird, it might be a bug in <mex.h> for R2018b.
