[ANNOUNCE] CMake 3.13.0 available for download

Robert Maynard
I am happy to announce that CMake 3.13.0 is now available for download at:
  https://cmake.org/download/

Documentation is available at:
  https://cmake.org/cmake/help/v3.13

Release notes appear below and are also published at
  https://cmake.org/cmake/help/v3.13/release/3.13.html

Some of the more significant changes in CMake 3.13 are:

* The Visual Studio Generators for VS 2010 and above learned to
  support the "INTERPROCEDURAL_OPTIMIZATION" target property and
  supporting "CheckIPOSupported" module.

* The "Green Hills MULTI" generator has been updated to include
  support for platform, architecture, and toolset selection.

* The "cmake" command gained the "-S <source_dir>" command line
  option to specify the location of the source directory. This option
  can be used independently of "-B".

* The "cmake" command gained the "-B <build_dir>" command line
  option to specify the location of the build directory. This option
  can be used independently of "-S".

* The "cmake" "-E create_symlink" command can now be used on
  Windows.

* The "target_link_directories()" command was created to specify
  link directories for targets and their dependents.

* The "target_link_options()" command was created to specify link
  options for targets and their dependents.

* The "target_link_libraries()" command may now be called to modify
  targets created outside the current directory. See policy "CMP0079".

* The "install(TARGETS)" command learned to install targets created
  outside the current directory.

* A "VS_DEBUGGER_COMMAND_ARGUMENTS" target property was created to
  set the debugging command line arguments with Visual Studio
  Generators for VS 2010 and above.

* A "VS_DEBUGGER_ENVIRONMENT" target property was created to set the
  debugging environment with Visual Studio Generators for VS 2010 and
  above.

* The "option()" command now honors an existing normal variable of
  the same name and does nothing instead of possibly creating a cache
  entry (or setting its type) and removing the normal variable. See
  policy "CMP0077".

* The "target_sources()" command now interprets relative source file
  paths as relative to the current source directory.  This simplifies
  incrementally building up a target's sources from subdirectories.
  The "CMP0076" policy was added to provide backward compatibility
  with the old behavior where required.


CMake 3.13 Release Notes
************************

Changes made since CMake 3.12 include the following.


New Features
============


Generators
----------

* The Visual Studio Generators for VS 2010 and above learned to
  support the "INTERPROCEDURAL_OPTIMIZATION" target property and
  supporting "CheckIPOSupported" module.

* The "Xcode" generator learned to configure more Xcode Scheme
  fields. See the "CMAKE_XCODE_GENERATE_SCHEME" variable.

* The "Green Hills MULTI" generator has been updated:

  * Added support for architecture selection through
    "CMAKE_GENERATOR_PLATFORM": e.g. "arm", "ppc", and "86".

  * Added support for toolset selection through
    "CMAKE_GENERATOR_TOOLSET", e.g. "comp_201205", "comp_201510",
    "comp_201722_beta".

  * Added support for platform selection through
    "GHS_TARGET_PLATFORM", e.g. "integrity", "linux", "standalone",
    etc.

  * No longer checks that "arm" based compilers are installed but
    ensures that the correct "gbuild.exe" exists.

  * No longer hard-codes ARM files, BSP, toolset, or OS locations.


Command-Line
------------

* The "cmake(1)" command gained the "-S <source_dir>" command line
  option to specify the location of the source directory. This option
  can be used independently of "-B".

* The "cmake(1)" command gained the "-B <build_dir>" command line
  option to specify the location of the build directory. This option
  can be used independently of "-S".

* The "cmake(1)" "-E create_symlink" command can now be used on
  Windows.


Commands
--------

* The "add_custom_command()" and "add_custom_target()" commands
  learned to support generator expressions in "WORKING_DIRECTORY"
  options.

* The "add_link_options()" command was created to add link options
  in the current directory.

* The "install(TARGETS)" command learned to install targets created
  outside the current directory.

* The "link_directories()" command gained options to control
  insertion position.

* The "list(SORT)" command gained options to control the comparison
  operation used to order the entries.

* The "math()" command gained options for hexadecimal.

* The "target_link_directories()" command was created to specify
  link directories for targets and their dependents.

* The "target_link_options()" command was created to specify link
  options for targets and their dependents.

* The "target_link_libraries()" command may now be called to modify
  targets created outside the current directory. See policy "CMP0079".


Variables
---------

* A "CMAKE_AUTOGEN_VERBOSE" variable was added to optionally
  increase the verbosity of "AUTOMOC", "AUTOUIC" and "AUTORCC" from
  within CMake project code.

* A "CMAKE_VS_GLOBALS" variable was added to initialize
  "VS_GLOBAL_<variable>" target properties on targets as they are
  created.


Properties
----------

* The "DEPLOYMENT_ADDITIONAL_FILES" target property was added to
  tell the "Visual Studio 9 2008" generator to specify additional
  files for deployment to WinCE devices for remote debugging.

* The "INTERFACE_LINK_DEPENDS" target property was created to
  specify transitive link dependencies on files.

* The "LINK_DEPENDS" target property learned to support "generator
  expressions".

* "LINK_DIRECTORIES" and "INTERFACE_LINK_DIRECTORIES" target
  properties were added to collect link directories for a target and
  its dependents.  Use the "target_link_directories()" command to set
  them.

* "LINK_OPTIONS" and "INTERFACE_LINK_OPTIONS" target properties were
  added to collect link options for a target and its dependents.  Use
  the "target_link_options()" command to set them.

* A "LINK_OPTIONS" directory property was added to collect link
  options for targets created under the current directory. Use the
  "add_link_options()" command to set it.

* A "STATIC_LIBRARY_OPTIONS" target property was created to specify
  archiver options to use when creating static libraries.

* A "VS_DEBUGGER_COMMAND_ARGUMENTS" target property was created to
  set the debugging command line arguments with Visual Studio
  Generators for VS 2010 and above.

* A "VS_DEBUGGER_ENVIRONMENT" target property was created to set the
  debugging environment with Visual Studio Generators for VS 2010 and
  above.

* The "VS_DEBUGGER_COMMAND" and "VS_DEBUGGER_WORKING_DIRECTORY"
  target properties now support generator expressions.


Modules
-------

* The "FindBoost" module gained a "Boost_ARCHITECTURE" option to
  specify a Boost architecture-specific library filename fragment.

* The "FindCURL" module learned to find debug and release variants
  separately.

* The "FindMatlab" module gained new components "ENGINE_LIBRARY" and
  "DATAARRAY_LIBRARY" to request finding the Matlab C++ Engine and
  DataArray libraries respectively.

* The "FindMatlab" module now explicitly exports mexFunction in
  Visual Studio.

* The "FindMatlab" module gained a new "MCC_COMPILER" component to
  request finding the Matlab Compiler add-on.

* The "FindPkgConfig" module gained an option to create imported
  targets in global scope.

* The "FindPkgConfig" module gained support for "<" and ">"
  operators for version checks in addition to the already supported
  operators ">=", "<=", and "=".

* Modules "FindPython3", "FindPython2" and "FindPython" gain
  capability to control order of resource lookup on macOS (Framework)
  and Windows (Registry).

* The "FindSubversion" module "Subversion_WC_INFO" command gained an
  "IGNORE_SVN_FAILURE" option to suppress failures, e.g. when the
  source tree is not under Subversion control.

* The "UseSWIG" module learned to manage target property
  "INCLUDE_DIRECTORIES" for "SWIG" compilation.


CTest
-----

* "ctest(1)" gained a "--progress" option to enable a live test
  progress summary when output goes to a terminal.


CPack
-----

* The "CPack DEB Generator" learned to split debug symbols into a
  corresponding .ddeb package when "CPACK_DEBIAN_DEBUGINFO_PACKAGE" is
  set.

* The "CPack DEB Generator" learned to honor the "SOURCE_DATE_EPOCH"
  environment variable when packaging files.  This is useful for
  generating reproducible packages.

* CPack gained a new "CPack External Generator" which is used to
  export the CPack metadata in a format that other software can
  understand. The intention of this generator is to allow external
  packaging software to take advantage of CPack's features when it may
  not be possible to use CPack for the entire packaging process.


Deprecated and Removed Features
===============================

* An explicit deprecation diagnostic was added for policies
  "CMP0055" through "CMP0063" ("CMP0054" and below were already
  deprecated). The "cmake-policies(7)" manual explains that the OLD
  behaviors of all policies are deprecated and that projects should
  port to the NEW behaviors.


Other Changes
=============

* The precompiled binaries provided on "cmake.org" now include
  qthelp- format documentation.

* The "option()" command now honors an existing normal variable of
  the same name and does nothing instead of possibly creating a cache
  entry (or setting its type) and removing the normal variable. See
  policy "CMP0077".

* The Makefile Generators learned to remove custom command and
  custom target byproducts during "make clean".

* The "target_sources()" command now interprets relative source file
  paths as relative to the current source directory.  This simplifies
  incrementally building up a target's sources from subdirectories.
  The "CMP0076" policy was added to provide backward compatibility
  with the old behavior where required.

* The "BundleUtilities" module may no longer be included at
  configure time. This was always a bug anyway. See policy "CMP0080".

* The "UseSWIG" module has changed strategy for target naming. See
  policy "CMP0078".

* The "LINK_DIRECTORIES" target property now expects absolute paths.
  See policy "CMP0081".

* The CPack generators have been moved into their own separate
  section in the documentation, rather than having the documentation
  in their internal implementation modules. These internal
  implementation modules are also no longer available to scripts that
  may have been incorrectly including them, because they should never
  have been available in the first place.
