This is + experimental and based on "Visual Studio 2017 RC" because this version + of VS has not been released. + +* :ref:`Visual Studio Generators` for VS 2010 and above learned to + place ``.natvis`` source files into VS project files properly. + +* The :generator:`Xcode` generator's rudimentary Swift language support + learned to honor a new :variable:`CMAKE_Swift_LANGUAGE_VERSION` variable + to tell Xcode what version of Swift is used by the source. + +* The :generator:`CodeLite` generator gained a new + :variable:`CMAKE_CODELITE_USE_TARGETS` option + to change project creation from projects to targets. + +Commands +-------- + +* The :command:`add_custom_command` command gained a new ``DEPFILE`` + option that works with the :generator:`Ninja` generator to provide + implicit dependency information to the build tool. + +* The :command:`cmake_parse_arguments` command gained a new ``PARSE_ARGV`` + mode to read arguments directly from ``ARGC`` and ``ARGV#`` + variables inside a :command:`function` body. + +* The :command:`export` command gained an ``ANDROID_MK`` option + to generate ``Android.mk`` files referencing CMake-built + libraries as prebuilts for the Android NDK build system. + +* The :command:`file(DOWNLOAD)` and :command:`file(UPLOAD)` commands gained + ``HTTPHEADER <HTTP-header>`` and ``USERPWD <username>:<password>`` options. + +* The :command:`find_library` and :command:`find_package` commands learned + to search in ``lib32/`` directories when the build targets a 32-bit + architecture. See the :prop_gbl:`FIND_LIBRARY_USE_LIB32_PATHS` global + property. + +* The :command:`find_package` command gained the possibility of + sorting compatible libraries by ``NAME`` or by ``NATURAL`` sorting by + setting the two new variables :variable:`CMAKE_FIND_PACKAGE_SORT_ORDER` + and :variable:`CMAKE_FIND_PACKAGE_SORT_DIRECTION`. + +* The :command:`if` command gained new boolean comparison operations + ``LESS_EQUAL``, ``GREATER_EQUAL``, ``STRLESS_EQUAL``, ``STRGREATER_EQUAL``, + ``VERSION_LESS_EQUAL``, and ``VERSION_GREATER_EQUAL``. + +* The :command:`install` command gained an ``EXPORT_ANDROID_MK`` + subcommand to install ``Android.mk`` files referencing installed + libraries as prebuilts for the Android NDK build system. + +* The :command:`string(TIMESTAMP)` and :command:`file(TIMESTAMP)` + commands gained support for the ``%a`` and ``%b`` placeholders. + These are the abbreviated weekday and month names. + +* The :command:`try_compile` command source file signature now honors + configuration-specific flags (e.g. :variable:`CMAKE_<LANG>_FLAGS_DEBUG`) + in the generated test project. Previously only the default such flags + for the current toolchain were used. See policy :policy:`CMP0066`. + +Variables +--------- + +* Variable :variable:`CMAKE_FIND_PACKAGE_SORT_ORDER` was added to control + the sorting mode of the :command:`find_package` command. + +* Variable :variable:`CMAKE_FIND_PACKAGE_SORT_DIRECTION` was added to control + the sorting direction the :command:`find_package` command. + +* :variable:`Toolchain files <CMAKE_TOOLCHAIN_FILE>` may now set a + :variable:`CMAKE_<LANG>_FLAGS_INIT` variable to initialize the + :variable:`CMAKE_<LANG>_FLAGS` cache entry the first time a language is + enabled in a build tree. + +* :variable:`Toolchain files <CMAKE_TOOLCHAIN_FILE>` may now set + :variable:`CMAKE_EXE_LINKER_FLAGS_INIT`, + :variable:`CMAKE_SHARED_LINKER_FLAGS_INIT`, and + :variable:`CMAKE_MODULE_LINKER_FLAGS_INIT` variables to initialize the + :variable:`CMAKE_EXE_LINKER_FLAGS`, + :variable:`CMAKE_SHARED_LINKER_FLAGS`, and + :variable:`CMAKE_MODULE_LINKER_FLAGS` cache entries the first time + a language is enabled in a build tree. + +Properties +---------- + +* On Apple platforms the :prop_tgt:`BUNDLE_EXTENSION` target property + now also applies to Frameworks and App Bundles. + +* A :prop_dir:`BINARY_DIR` directory property was added to get the + absolute path to the binary directory corresponding to the source + directory on which the property is read. + +* A :prop_dir:`BUILDSYSTEM_TARGETS` directory property was added to + get the list of logical buildsystem target names added by the + project in a directory. + +* A :prop_tgt:`LINK_WHAT_YOU_USE` target property and supporting + :variable:`CMAKE_LINK_WHAT_YOU_USE` variable were introduced + to detect (on UNIX) shared libraries that are linked but not + needed by running ``ldd -r -u``. + +* A :prop_dir:`SOURCE_DIR` directory property was added to get the + absolute path to the source directory associated with a directory. + +* A :prop_dir:`SUBDIRECTORIES` directory property was added to + get the list of subdirectories added by a project in a directory. + +* A :prop_tgt:`VS_SDK_REFERENCES` target property was added to tell + :ref:`Visual Studio Generators` to reference the named SDKs. + +* A :prop_sf:`VS_TOOL_OVERRIDE` source file property was created to tell + :ref:`Visual Studio Generators` what tool to use for a source file. + +* The :prop_tgt:`WINDOWS_EXPORT_ALL_SYMBOLS` target property now applies + to executable targets with the :prop_tgt:`ENABLE_EXPORTS` property set. + +* A :prop_sf:`XCODE_FILE_ATTRIBUTES` source file property was + added to tell the :generator:`Xcode` generator to generate + custom content in the Xcode project attributes for the file. + +Modules +------- + +* An :module:`AndroidTestUtilities` module was added to manage transfer + of test data to an Android device. + +* The :module:`CheckFortranSourceCompiles` module macro + ``CHECK_Fortran_SOURCE_COMPILES`` gained a ``SRC_EXT`` option + to specify a custom test Fortran source file extension. + +* The :module:`ExternalProject` module gained ``HTTP_USERNAME`` and + ``HTTP_PASSWORD`` options to set http download credentials. + +* The :module:`ExternalProject` module gained a ``HTTP_HEADER`` + option to add http download headers. + +* The :module:`FindBISON` module ``BISON_TARGET`` macro learned a new + ``REPORT_FILE`` option to specify the bison ``--report-file=`` option. + +* The :module:`FindBZip2` module now provides imported targets. + +* A :module:`FindICU` module was introduced to find the International + Components for Unicode (ICU) libraries and programs. + +* The :module:`FindMatlab` module learned to find the SIMULINK and MAT + components. + +* The :module:`FindMatlab` module :command:`matlab_add_mex` command learned + to add executables and modules. + +* The :module:`FindMatlab` module :command:`matlab_add_unit_test` command + learned to support inline Matlab test code. + +* The :module:`FindOpenCL` module now provides imported targets. + +* The :module:`FindOpenMP` module learned to detect the OpenMP + version (specification date) from the compiler. + +* A :module:`FindVulkan` module was added. + +* The :module:`GenerateExportHeader` module learned a new + ``CUSTOM_CONTENT_FROM_VARIABLE`` option to specify a variable + containing custom content for inclusion in the generated header. + +* The :module:`GNUInstallDirs` module gained a new + :command:`GNUInstallDirs_get_absolute_install_dir` command. + +* The :module:`UseJava` module gained APIs to "export" jar targets + for use by external CMake projects.
