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:`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.

|
|
of a custom absolute installation prefix outside
|
|
of the ProgramFiles folders.
|
|
|
|

|
|
|
|
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.
