CMake 3.5 Release Notes¶
Changes made since CMake 3.4 include the following.
New Features¶
GUI¶
- The - cmake-gui(1)gained options to control warnings about deprecated functionality.
- The - cmake-gui(1)learned an option to set the toolset to be used with VS IDE and Xcode generators, much like the existing- -Toption to- cmake(1).
- The - cmake-gui(1)gained a Regular Expression Explorer which may be used to create and evaluate regular expressions in real-time. The explorer window is available via the- Toolsmenu.
Command-Line¶
- The - -Wdevand- -Wno-dev- cmake(1)options now also enable and suppress the deprecated warnings output by default.
- The suppression of developer warnings as errors can now be controlled with the new - -Werror=devand- -Wno-error=dev- cmake(1)options.
- The - cmake(1)- -Ecommand-line tools- copy,- copy_if_different,- copy_directory, and- make_directorylearned to support multiple input files or directories.
Commands¶
- The - cmake_parse_arguments()command is now implemented natively. The- CMakeParseArgumentsmodule remains as an empty placeholder for compatibility.
- The - install(DIRECTORY)command learned to support- generator expressionsin the list of directories.
Variables¶
- The - CMAKE_ERROR_DEPRECATEDvariable can now be set using the- -Werror=deprecatedand- -Wno-error=deprecated- cmake(1)options.
- The - CMAKE_WARN_DEPRECATEDvariable can now be set using the- -Wdeprecatedand- -Wno-deprecated- cmake(1)options.
Properties¶
- The - VS_GLOBAL_<variable>target property is now implemented for VS 2010 and above. Previously it worked only in VS 2008 and below.
Modules¶
- The - ExternalProjectmodule learned a new- GIT_REMOTE_NAMEoption to control the- git clone --originvalue.
- The - FindBoostmodule now provides imported targets such as- Boost::boostand- Boost::filesystem.
- The - FindFLEXmodule- FLEX_TARGETmacro learned a new- DEFINES_FILEoption to specify a custom output header to be generated.
- The - FindGTestmodule now provides imported targets.
- The - FindGTK2module, when- GTK2_USE_IMPORTED_TARGETSis enabled, now sets- GTK2_LIBRARIESto contain the list of imported targets instead of the paths to the libraries. Moreover it now sets a new- GTK2_TARGETSvariable containing all the targets imported.
- The - FindOpenMPmodule learned to support Clang.
- The - FindOpenSSLmodule gained a new- OPENSSL_MSVC_STATIC_RToption to search for libraries using the MSVC static runtime.
- The - FindPNGmodule now provides imported targets.
- The - FindTIFFmodule now provides imported targets.
- A - FindXalanCmodule was introduced to find the Apache Xalan-C++ XSL transform processing library.
- The - FindXercesCmodule now provides imported targets.
Platforms¶
- Support was added for the ARM Compiler (arm.com) with compiler id - ARMCC.
- A new platform file for cross-compiling in the Cray Linux Environment to target compute nodes was added. See Cross Compiling for the Cray Linux Environment for usage details. 
- The - Compile Featuresfunctionality is now aware of features supported by Clang compilers on Windows (MinGW).
- When building for embedded Apple platforms like iOS CMake learned to build and install combined targets which contain both a device and a simulator build. This behavior can be enabled by setting the - IOS_INSTALL_COMBINEDtarget property.
CPack¶
- The - CPack DragNDrop Generatorlearned new variable to specify AppleScript file run to customize appearance of- DragNDropinstaller folder, including background image setting using supplied PNG or multi-resolution TIFF file. See the- CPACK_DMG_DS_STORE_SETUP_SCRIPTand- CPACK_DMG_BACKGROUND_IMAGEvariables.
- The - CPack DEB Generatorlearned to set the optional config file- Sourcefield using a monolithic or per-component variable. See- CPACK_DEBIAN_PACKAGE_SOURCE.
- The - CPack DEB Generatorlearned to set Package, Section and Priority control fields per-component. See variables- CPACK_DEBIAN_<COMPONENT>_PACKAGE_SECTIONand- CPACK_DEBIAN_<COMPONENT>_PACKAGE_PRIORITY.
- The - CPack DragNDrop Generatorlearned to add multi-lingual SLAs to a DMG which is presented to the user when they try to mount the DMG. See the- CPACK_DMG_SLA_LANGUAGESand- CPACK_DMG_SLA_DIRvariables for details.
- The - CPack NSIS Generatorlearned new variables to add bitmaps to the installer. See the- CPACK_NSIS_MUI_WELCOMEFINISHPAGE_BITMAPand- CPACK_NSIS_MUI_UNWELCOMEFINISHPAGE_BITMAPvariables.
- The - CPack RPM Generatorlearned to set Name and Group control fields per-component. See- CPACK_RPM_<component>_PACKAGE_NAMEand- CPACK_RPM_<component>_PACKAGE_GROUP.
Other¶
- Warnings about deprecated functionality are now enabled by default. They may be suppressed with - -Wno-deprecatedor by setting the- CMAKE_WARN_DEPRECATEDvariable to false.
Deprecated and Removed Features¶
- The - cmake(1)- -E timecommand now properly passes arguments with spaces or special characters through to the child process. This may break scripts that worked around the bug with their own extra quoting or escaping.
- The - Xcodegenerator was fixed to escape backslashes in strings consistently with other generators. Projects that previously worked around the inconsistecy with an extra level of backslashes conditioned on the Xcode generator must be updated to remove the workaround for CMake 3.5 and greater.
Other Changes¶
- The - Visual Studio 14 2015generator learned to map the- /debug:fastlinklinker flag to the- .vcxprojfile property.
- The - FindGTK2module now configures the- GTK2::sigc++imported target to enable c++11 on its dependents when using sigc++ 2.5.1 or higher.
- The precompiled Windows binary provided on - cmake.orgis now a- .msipackage instead of an installer executable. One may need to manually uninstall CMake versions lower than 3.5 before installing the new package.
