See generator expression documentation + for caveats. + +* The :generator:`Xcode` generator learned to support the ``COMPILE_LANGUAGE`` + :manual:`generator expression <cmake-generator-expressions(7)>` in + target-wide :prop_tgt:`COMPILE_DEFINITIONS` and + :prop_tgt:`INCLUDE_DIRECTORIES`. It previously supported only + :prop_tgt:`COMPILE_OPTIONS` and :command:`file(GENERATE)`. + See generator expression documentation for caveats. + +Commands +-------- + +* :command:`add_library` and :command:`add_executable` commands can now be + called without any sources and will not complain as long as sources are + added later via the :command:`target_sources` command. + +* The :command:`file(DOWNLOAD)` and :command:`file(UPLOAD)` commands + gained ``NETRC`` and ``NETRC_FILE`` options to specify use of a + ``.netrc`` file. + +* The :command:`target_compile_definitions` command learned to set the + :prop_tgt:`INTERFACE_COMPILE_DEFINITIONS` property on + :ref:`Imported Targets`. + +* The :command:`target_compile_features` command learned to set the + :prop_tgt:`INTERFACE_COMPILE_FEATURES` property on :ref:`Imported Targets`. + +* The :command:`target_compile_options` command learned to set the + :prop_tgt:`INTERFACE_COMPILE_OPTIONS` property on :ref:`Imported Targets`. + +* The :command:`target_include_directories` command learned to set the + :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` property on + :ref:`Imported Targets`. + +* The :command:`target_sources` command learned to set the + :prop_tgt:`INTERFACE_SOURCES` property on :ref:`Imported Targets`. + +* The :command:`target_link_libraries` command learned to set the + :prop_tgt:`INTERFACE_LINK_LIBRARIES` property on :ref:`Imported Targets`. + +Variables +--------- + +* A :variable:`CMAKE_GENERATOR_INSTANCE` variable was introduced + to hold the selected instance of the generator's corresponding + native tools if multiple are available. This is used by the + :generator:`Visual Studio 15 2017` generator to hold the + selected instance of Visual Studio persistently. + +* A :variable:`CMAKE_INSTALL_DEFAULT_DIRECTORY_PERMISSIONS` variable was added + to enable setting of default permissions for directories created implicitly + during installation of files by :command:`install` and + :command:`file(INSTALL)`, e.g. during ``make install``. + +* A :variable:`CMAKE_JOB_POOLS` variable was added specify a value to use for + the :prop_gbl:`JOB_POOLS` property. This enables control over build + parallelism with command line configuration parameters when using the Ninja + generator. + +* The :variable:`CMAKE_NETRC` and :variable:`CMAKE_NETRC_FILE` variables + were added to specify use of a ``.netrc`` file by the + :command:`file(DOWNLOAD)` and :command:`file(UPLOAD)` commands and + the :module:`ExternalProject` module. + +* A :variable:`CMAKE_CUDA_SEPARABLE_COMPILATION` variable was added to + initialize the :prop_tgt:`CUDA_SEPARABLE_COMPILATION` target property + on targets when they are created. + +Properties +---------- + +* The :prop_sf:`COMPILE_DEFINITIONS` source file property learned to support + :manual:`generator expressions <cmake-generator-expressions(7)>`. + +* A :prop_sf:`COMPILE_OPTIONS` source file property was added to manage list + of options to pass to the compiler. + +* An :prop_tgt:`IMPORTED_GLOBAL` target property was added to indicate + whether an :ref:`IMPORTED target <Imported Targets>` is globally visible. + It is automatically set to a true value for targets created with the + ``GLOBAL`` option to :command:`add_library` or :command:`add_executable`. + Additionally, project code may now *promote* a local imported target + to be globally visible by setting this property to ``TRUE``. + +* An :prop_sf:`INCLUDE_DIRECTORIES` source file property was added to specify + list of preprocessor include file search directories. + +* Source file properties :prop_sf:`VS_SHADER_DISABLE_OPTIMIZATIONS` and + :prop_sf:`VS_SHADER_ENABLE_DEBUG` have been added to specify more + details of ``.hlsl`` sources with :ref:`Visual Studio Generators`. + +Modules +------- + +* The :module:`CheckIncludeFiles` module :command:`CHECK_INCLUDE_FILES` + command gained a ``LANGUAGE`` option to specify whether to check using the + ``C`` or ``CXX`` compiler. + +* The :module:`CMakePackageConfigHelpers` module + :command:`write_basic_package_version_file` command learned a new + ``SameMinorVersion`` mode for the ``COMPATIBILITY`` argument. + +* The :module:`ExternalProject` module learned to substitute ``<DOWNLOAD_DIR>`` + in comments, commands, working directory and byproducts. + +* The :module:`ExternalProject` module gained ``NETRC`` and ``NETRC_FILE`` + options to specify use of a ``.netrc`` file. + +* A new :module:`FetchContent` module was added which supports populating + content at configure time using any of the download/update methods + supported by :command:`ExternalProject_Add`. This allows the content + to be used immediately during the configure stage, such as with + :command:`add_subdirectory`, etc. Hierarchical project structures are + well supported, allowing parent projects to override the content details + of child projects and ensuring content is not populated multiple times + throughout the whole project tree. + +* The :module:`FindBLAS` and :module:`FindLAPACK` modules learned to support + `FLAME`_ ``blis`` and ``libflame``. + +* The :module:`FindDoxygen` module :command:`doxygen_add_docs` function + now supports a new ``DOXYGEN_VERBATIM_VARS`` list variable. Any + ``DOXYGEN_...`` variable contained in that list will bypass the automatic + quoting logic, leaving its contents untouched when transferring them to the + output ``Doxyfile``. + +* A :module:`FindIconv` module was added to locate iconv support. + +* The :module:`GenerateExportHeader` module ``GENERATE_EXPORT_HEADER`` command + gained an ``INCLUDE_GUARD_NAME`` option to change the name of the include + guard symbol written to the generated export header. + Additionally, it now adds a comment after the closing ``#endif`` on the + generated export header's include guard. + +* The :module:`UseJava` module ``add_jar`` command gained a + ``GENERATE_NATIVE_HEADERS`` option to generate native header files + using ``javac -h`` for ``javac`` 1.8 or above. This supersedes + ``create_javah``, which no longer works with JDK 1.10 and above due + to removal of the ``javah`` tool by `JEP 313`_. + +.. _`FLAME`: https://github.com/flame +.. _`JEP 313`: http://openjdk.java.net/jeps/313 + +Autogen +------- + +* When using :prop_tgt:`AUTOMOC` or :prop_tgt:`AUTOUIC`, CMake now starts + multiple parallel ``moc`` or ``uic`` processes to reduce the build time. + A new :variable:`CMAKE_AUTOGEN_PARALLEL` variable and + :prop_tgt:`AUTOGEN_PARALLEL` target property may be set to specify the + number of parallel ``moc`` or ``uic`` processes to start. The default + is derived from the number of CPUs on the host. + +CTest +----- + +* The :command:`ctest_start` command no longer sets + :variable:`CTEST_RUN_CURRENT_SCRIPT` due to issues with scoping if it is + called from inside a function. Instead, it sets an internal variable in + CTest. However, setting :variable:`CTEST_RUN_CURRENT_SCRIPT` to 0 at the + global scope still prevents the script from being re-run at the end. + +CPack +----- + +* :manual:`cpack(1)` gained ``--trace`` and ``--trace-expand`` options. + +* The :cpack_gen:`CPack IFW Generator` gained new + :variable:`CPACK_IFW_PACKAGE_REMOVE_TARGET_DIR` variable to control + if the target directory should not be deleted when uninstalling. + +* The :cpack_gen:`CPack RPM Generator` learned to enable enforcing of execute + privileges on programs and shared libraries. + See :variable:`CPACK_RPM_INSTALL_WITH_EXEC` variable. + +* A :variable:`CPACK_INSTALL_DEFAULT_DIRECTORY_PERMISSIONS` variable was added + which serves the same purpose during packaging (e.g. ``make package``) as the + :variable:`CMAKE_INSTALL_DEFAULT_DIRECTORY_PERMISSIONS` variable serves during + installation (e.g. ``make install``). + +Other +----- + +* :ref:`Alias Targets` may now alias :ref:`Imported Targets` that are + created with the ``GLOBAL`` option to :command:`add_library`. + +* :ref:`Interface Libraries` may now have custom properties set on them if + they start with either an underscore (``_``) or a lowercase ASCII character. + The original intention was to only allow properties which made sense for + ``INTERFACE`` libraries, but it also blocked usage of custom properties. + +* The :manual:`cmake(1)` ``--open <dir>`` command-line option was added + to open generated IDE projects like Visual Studio solutions or Xcode + projects. + +Deprecated and Removed Features +=============================== + +* An explicit deprecation diagnostic was added for policies ``CMP0037`` + through ``CMP0054`` (``CMP0036`` and below were already deprecated). + The :manual:`cmake-policies(7)` manual explains that the OLD behaviors + of all policies are deprecated and that projects should port to the + NEW behaviors. + +* The ``KDevelop3`` generator has been removed. + +Other Changes +============= + +* Policy :policy:`CMP0037` no longer reserves target names associated + with optional features, such as ``test`` and ``package``, unless + the corresponding feature is enabled. + +* The :module:`FindOpenGL` module now prefers GLVND libraries if available. + See policy :policy:`CMP0072`. + +* The minimum deployment target set in the + :variable:`CMAKE_OSX_DEPLOYMENT_TARGET` variable used to be only + applied for macOS regardless of the selected SDK. It is now properly + set for the target platform selected by :variable:`CMAKE_OSX_SYSROOT`. + For example, if the sysroot variable specifies an iOS SDK then the + value in ``CMAKE_OSX_DEPLOYMENT_TARGET`` is interpreted as minimum + iOS version. + +* The :generator:`Xcode` generator behavior of generating one project + file per :command:`project()` command may now be controlled with the + :variable:`CMAKE_XCODE_GENERATE_TOP_LEVEL_PROJECT_ONLY` variable. + This could be useful to speed up the CMake generation step for + large projects and to work-around a bug in the ``ZERO_CHECK`` logic. + +* Since the ``CMakeCache.txt`` format does not support newlines in values, + values containing newlines are now truncated before writing to the file. + In addition, a warning comment is written to the cache file, and a warning + message is displayed to the user on the console. + +Updates +======= + +Changes made since CMake 3.11.0 include the following. + +3.11.1 +------ + +* The :module:`CheckIncludeFile` module ``check_include_file`` macro, + :module:`CheckIncludeFileCXX` module ``check_include_file_cxx`` macro, + and :module:`CheckIncludeFiles` module ``check_include_files`` macro + were taught to honor the ``CMAKE_REQUIRED_LIBRARIES`` variable in + CMake 3.11.0. This has been reverted due to changing behavior of + checks for existing projects. It may be restored in the future + with a policy for compatibility. + +3.11.2 +------ + +* Calling :command:`add_library` to create an alias of an imported + target that is not globally visible now causes an error again as + it did prior to 3.11.0. This diagnostic was accidentally dropped + from CMake 3.11.0 and 3.11.1 by the change to allow globally visible + imported targets to be aliased. + +* The :module:`FindQt4` module ``qt4_wrap_cpp``, ``qt4_wrap_ui`` and + ``qt4_add_resources`` macros now set :prop_sf:`SKIP_AUTOMOC` and + :prop_sf:`SKIP_AUTOUIC` on their generated files. These files never + need to be processed by moc or uic, and we must say so explicitly to + account for policy :policy:`CMP0071`. + +3.11.3 +------ + +* CMake 3.11.0 introduced support for resolving symbolic links on + Windows in code paths that typically do so on UNIX. This has been + reverted due to breakage on ``subst`` drives. |
