| .. contents:: | |
| Changes made since CMake 3.6 include the following. | |
| New Features | |
| ============ | |
| Platforms | |
| --------- | |
| * CMake now supports :ref:`Cross Compiling for Android` with simple | |
| toolchain files. | |
| * The Clang compiler is now supported on AIX. | |
| Generators | |
| ---------- | |
| * The :generator:`Ninja` generator learned to conditionally support | |
| Fortran when using a ``ninja`` tool that has the necessary features. | |
| See generator documentation for details. | |
| * The :generator:`Ninja` generator learned to produce phony targets | |
| of the form ``sub/dir/{test,install,package}`` to drive the build | |
| of a subdirectory installation, test or packaging target. | |
| This is equivalent to ``cd sub/dir; make {test,install,package}`` | |
| with :ref:`Makefile Generators`. | |
| * The :generator:`Visual Studio 15 2017` generator was added. 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 | |

| :variable:`CPACK_WIX_ROOT_FEATURE_DESCRIPTION` to allow the specification | |
| of a custom title and description for the root feature element. | |
| Other | |
| ----- | |
| * :manual:`cmake(1)` gained a ``-E capabilities`` option to provide a | |
| machine-readable (JSON) description of the capabilities of the | |
| cmake tool (available generators, etc.). | |
| * A new :manual:`cmake-server(7)` mode was added to provide semantic | |
| information about a CMake-generated buildsystem to clients through | |
| a JSON protocol. Currently all protocols are experimental and subject | |
| to change. | |
| * The :manual:`cmake(1)` command learned a ``--trace-source=<file>`` option. | |

| Deprecated and Removed Features | |
| =============================== | |
| * We no longer provide Linux i386 binaries for download from ``cmake.org`` | |
| for new versions of CMake. | |
| * Vim support files ``cmake-indent.vim``, ``cmake-syntax.vim``, and | |
| ``cmake-help.vim`` have been removed in favor of the files now provided | |
| from the `vim-cmake-syntax`_ project. | |
| * Support for building CMake itself with some compilers was dropped: | |
| * Visual Studio 7.1 and 2005 -- superseded by VS 2008 and above | |
| * MinGW.org mingw32 -- superseded by MSYS2 mingw32 and mingw64 | |
| CMake still supports generating build systems for other projects using | |
| these compilers. | |
| Other Changes | |
| ============= | |
| * The Fortran dependency scanner learned to support the syntax of | |
| `Fortran Submodules`_. | |
| * Vim support files ``indent/cmake.vim`` and ``syntax/cmake.vim`` | |
| from the `vim-cmake-syntax`_ project are now distributed with CMake. | |
