[ANNOUNCE] CMake 3.6.0-rc4 now ready for testing!




I am proud to announce the fourth CMake 3.6 release candidate.

Sources and binaries are available at:
  https://cmake.org/download/

Documentation is available at:
  https://cmake.org/cmake/help/v3.6

Release notes appear below and are also published at
  https://cmake.org/cmake/help/v3.6/release/3.6.html

Some of the more significant features of CMake 3.6 are:

* The "Visual Studio 14 2015" generator learned to support the
  Clang/C2 toolsets, e.g. with the "-T v140_clang_3_7" option. This
  feature is experimental.

* The "list()" command gained a "FILTER" sub-command to filter list
  elements by regular expression.

* A "CMAKE_TRY_COMPILE_TARGET_TYPE" variable was added to optionally
  tell the "try_compile()" command to build a static library instead
  of an executable.  This is useful for cross-compiling toolchains
  that cannot link binaries without custom flags or scripts.

* A "<LANG>_CLANG_TIDY" target property and supporting
  "CMAKE_<LANG>_CLANG_TIDY" variable were introduced to tell the
  Makefile Generators and the "Ninja" generator to run "clang-tidy"
  along with the compiler for "C" and "CXX" languages.

* The "ExternalProject" module leared the "GIT_SHALLOW 1" option to
  perform a shallow clone of a Git repository.

* The "ExternalProject" module learned to initialize Git submodules
  recursively and also to initialize new submodules on updates.  Use
  the "GIT_SUBMODULES" option to restrict which submodules are
  initalized and updated.

* The "InstallRequiredSystemLibraries" module learned a new
  "CMAKE_INSTALL_UCRT_LIBRARIES" option to enable app-local deployment
  of the Windows Universal CRT libraries with Visual Studio 2015.

* The "Compile Features" functionality is now aware of features
  supported by Intel C++ compilers versions 12.1 through 16.0 on UNIX
  platforms.

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

* The "CMakeForceCompiler" module and its macros are now deprecated.
  See module documentation for an explanation.

* The "Visual Studio 7 .NET 2003" generator is now deprecated and
  will be removed in a future version of CMake.

* The "Visual Studio 7" generator (for VS .NET 2002) has been
  removed. It had been deprecated since CMake 3.3.

* The "Visual Studio 6" generator has been removed. It had been
  deprecated since CMake 3.3.



CMake 3.6 Release Notes
***********************

Changes made since CMake 3.5 include the following.


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


Generators
----------

* The "Ninja" generator learned to produce phony targets of the form
  "sub/dir/all" to drive the build of a subdirectory. This is
  equivalent to "cd sub/dir; make all" with Makefile Generators.

* The "Ninja" generator now includes system header files in build
  dependencies to ensure correct re-builds when system packages are
  updated.

* The "Visual Studio 14 2015" generator learned to support the
  Clang/C2 toolsets, e.g. with the "-T v140_clang_3_7" option. This
  feature is experimental.


Commands
--------

* The "add_custom_command()" and "add_custom_target()" commands
  learned how to use the "CROSSCOMPILING_EMULATOR" executable target
  property.

* The "install()" command learned a new "EXCLUDE_FROM_ALL" option to
  leave installation rules out of the default installation.

* The "list()" command gained a "FILTER" sub-command to filter list
  elements by regular expression.

* The "string(TIMESTAMP)" and "file(TIMESTAMP)" commands gained
  support for the "%s" placeholder.  This is the number of seconds
  since the UNIX Epoch.


Variables
---------

* A "CMAKE_DEPENDS_IN_PROJECT_ONLY" variable was introduced to tell
  Makefile Generators to limit dependency scanning only to files in
  the project source and build trees.

* A new "CMAKE_HOST_SOLARIS" variable was introduced to indicate
  when CMake is running on an Oracle Solaris host.

* A "CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES" variable was added
  for use by toolchain files to specify system include directories to
  be appended to all compiler command lines.

* The "CMAKE_<LANG>_STANDARD_LIBRARIES" variable is now documented.
  It is intended for use by toolchain files to specify system
  libraries to be added to all linker command lines.

* A "CMAKE_NINJA_OUTPUT_PATH_PREFIX" variable was introduced to tell
  the "Ninja" generator to configure the generated "build.ninja" file
  for use as a "subninja".

* A "CMAKE_TRY_COMPILE_PLATFORM_VARIABLES" variable was added for
  use by toolchain files to specify platform-specific variables that
  must be propagated by the "try_compile()" command into test
  projects.

* A "CMAKE_TRY_COMPILE_TARGET_TYPE" variable was added to optionally
  tell the "try_compile()" command to build a static library instead
  of an executable.  This is useful for cross-compiling toolchains
  that cannot link binaries without custom flags or scripts.


Properties
----------

* A "DEPLOYMENT_REMOTE_DIRECTORY" target property was introduced to
  tell the "Visual Studio 9 2008" and "Visual Studio 8 2005"
  generators to generate the "remote directory" for WinCE project
  deployment and debugger settings.

* A "<LANG>_CLANG_TIDY" target property and supporting
  "CMAKE_<LANG>_CLANG_TIDY" variable were introduced to tell the
  Makefile Generators and the "Ninja" generator to run "clang-tidy"
  along with the compiler for "C" and "CXX" languages.

* A "TIMEOUT_AFTER_MATCH" test property was introduced to optionally
  tell CTest to enforce a secondary timeout after matching certain
  output from a test.

* A "VS_CONFIGURATION_TYPE" target property was introduced to
  specify a custom project file type for Visual Studio Generators
  supporting VS 2010 and above.

* A "VS_STARTUP_PROJECT" directory property was introduced to
  specify for Visual Studio Generators the default startup project for
  generated solutions (".sln" files).


Modules
-------

* The "CMakePushCheckState" module now pushes/pops/resets the
  variable "CMAKE_EXTRA_INCLUDE_FILE" used in "CheckTypeSize".

* The "ExternalProject" module leared the "GIT_SHALLOW 1" option to
  perform a shallow clone of a Git repository.

* The "ExternalProject" module learned to initialize Git submodules
  recursively and also to initialize new submodules on updates.  Use
  the "GIT_SUBMODULES" option to restrict which submodules are
  initalized and updated.

* The "ExternalProject" module leared the "DOWNLOAD_NO_EXTRACT 1"
  argument to skip extracting the file that is downloaded (e.g., for
  self-extracting shell installers or ".msi" files).

* The "ExternalProject" module now uses "TLS_VERIFY" when fetching
  from git repositories.

* The "FindBLAS" and "FindLAPACK" modules learned to support
  OpenBLAS.

* The "FindCUDA" module learned to find the "cublas_device" library.

* The "FindGTest" module "gtest_add_tests" function now causes CMake
  to automatically re-run when test sources change so that they can be
  re-scanned.

* The "FindLTTngUST" module was introduced to find the LTTng-UST
  library.

* The "FindPkgConfig" module learned to optionally create imported
  targets for the libraries it has found.

* The "FindProtobuf" module learned to provide a "Protobuf_VERSION"
  variable and check the version number requested in a
  "find_package()" call.

* The "InstallRequiredSystemLibraries" module learned a new
  "CMAKE_INSTALL_UCRT_LIBRARIES" option to enable app-local deployment
  of the Windows Universal CRT libraries with Visual Studio 2015.


Platforms
---------

* The Clang compiler is now supported on CYGWIN.

* Support was added for the Bruce C Compiler with compiler id
  "Bruce".


CTest
-----

* The "ctest_update()" command now looks at the
  "CTEST_GIT_INIT_SUBMODULES" variable to determine whether submodules
  should be updated or not before updating.

* The "ctest_update()" command will now synchronize submodules on an
  update. Updates which add submodules or change a submodule's URL
  will now be pulled properly.


CPack
-----

* The "CPackDeb" module learned how to handle "$ORIGIN" in
  "CMAKE_INSTALL_RPATH" when "CPACK_DEBIAN_PACKAGE_SHLIBDEPS" is used
  for dependency auto detection.

* The "CPackDeb" module learned how to generate "DEBIAN/shlibs"
  contorl file when package contains shared libraries.

* The "CPackDeb" module learned how to generate "DEBIAN/postinst"
  and "DEBIAN/postrm" files if the package installs libraries in
  ldconfig- controlled locations (e.g. "/lib/", "/usr/lib/").

* The "CPackDeb" module learned how to generate dependencies between
  Debian packages if multi-component setup is used and
  "CPACK_COMPONENT_<compName>_DEPENDS" variables are set. For backward
  compatibility this feature is disabled by default. See
  "CPACK_DEBIAN_ENABLE_COMPONENT_DEPENDS".

* The "CPackDeb" module learned how to set custom package file names
  including how to generate properly-named Debian packages:

     <PackageName>_<VersionNumber>-<DebianRevisionNumber>_<DebianArchitecture>.deb

  For backward compatibility this feature is disabled by default. See
  "CPACK_DEBIAN_FILE_NAME" and "CPACK_DEBIAN_<COMPONENT>_FILE_NAME".

* The "CPackDeb" module learned how to set the package release
  number ("DebianRevisionNumber" in package file name when used in
  combination with "DEB-DEFAULT" value set by
  "CPACK_DEBIAN_FILE_NAME").  See "CPACK_DEBIAN_PACKAGE_RELEASE".

* The "CPackDeb" module learned how to set the package architecture
  per-component.  See "CPACK_DEBIAN_<COMPONENT>_PACKAGE_ARCHITECTURE".

* The "CPackDMG" module learned a new option to tell the CPack
  "DragNDrop" generaor to skip the "/Applications" symlink. See the
  "CPACK_DMG_DISABLE_APPLICATIONS_SYMLINK" variable.

* The "CPackIFW" module gained a new "cpack_ifw_update_repository()"
  command to update a QtIFW-specific repository from a remote
  repository.

* The "CPackRPM" module learned how to set RPM "dist" tag as part of
  RPM "Release:" tag when enabled (mandatory on some Linux
  distributions for e.g. on Fedora). See
  "CPACK_RPM_PACKAGE_RELEASE_DIST".

* The "CPackRPM" module learned how to set default values for owning
  user/group and file/directory permissions of package content. See
  "CPACK_RPM_DEFAULT_USER", "CPACK_RPM_DEFAULT_GROUP",
  "CPACK_RPM_DEFAULT_FILE_PERMISSIONS",
  "CPACK_RPM_DEFAULT_DIR_PERMISSIONS" and their per component
  counterparts.

* The "CPackRPM" module learned how to set user defined package file
  names, how to specify that rpmbuild should decide on file name
  format as well as handling of multiple rpm packages generated by a
  single user defined spec file. See "CPACK_RPM_PACKAGE_NAME" and
  "CPACK_RPM_<component>_PACKAGE_NAME".

* The "CPackRPM" module learned how to correctly handle symlinks
  that are pointing outside generated packages.


Other
-----

* The "Compile Features" functionality is now aware of features
  supported by Intel C++ compilers versions 12.1 through 16.0 on UNIX
  platforms.


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

* The "CMakeForceCompiler" module and its macros are now deprecated.
  See module documentation for an explanation.

* The "find_library()", "find_path()", and "find_file()" commands no
  longer search in installation prefixes derived from the "PATH"
  environment variable on non-Windows platforms.  This behavior was
  added in CMake 3.3 to support Windows hosts but has proven
  problematic on UNIX hosts. Users that keep some "<prefix>/bin"
  directories in the "PATH" just for their tools do not necessarily
  want any supporting "<prefix>/lib" directories searched.  One may
  set the "CMAKE_PREFIX_PATH" environment variable with a ;-list of
  prefixes that are to be searched.

* The "Visual Studio 7 .NET 2003" generator is now deprecated and
  will be removed in a future version of CMake.

* The "Visual Studio 7" generator (for VS .NET 2002) has been
  removed. It had been deprecated since CMake 3.3.

* The "Visual Studio 6" generator has been removed. It had been
  deprecated since CMake 3.3.


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

* The precompiled OS X binary provided on "cmake.org" now requires
  OS X 10.7 or newer.

* On Linux and FreeBSD platforms, when building CMake itself from
  source and not using a system-provided libcurl, OpenSSL is now used
  by default if it is found on the system.  This enables SSL/TLS
  support for commands supporting network communication via "https",
  such as "file(DOWNLOAD)", "file(UPLOAD)", and "ctest_submit()".

* The "cmake(1)" "--build" command-line tool now rejects multiple
  "-- target" options with an error instead of silently ignoring all
  but the last one.

* "AUTOMOC" now diagnoses name collisions when multiple source files
  in different directories use "#include <moc_foo.cpp>" with the same
  name (because the generated "moc_foo.cpp" files would collide).

* The "FindBISON" module "BISON_TARGET" macro now supports special
  characters by passing the "VERBATIM" option to internal
  "add_custom_command()" calls.  This may break clients that added
  escaping manually to work around the bug.

* The "FindFLEX" module "FLEX_TARGET" macro now supports special
  characters by passing the "VERBATIM" option to internal
  "add_custom_command()" calls.  This may break clients that added
  escaping manually to work around the bug.

* The "FindProtobuf" module input and output variables were all
  renamed from "PROTOBUF_" to "Protobuf_" for consistency with other
  find modules. Input variables of the old case will be honored if
  provided, and output variables of the old case are always provided.

* The "CPackRPM" module now supports upper cased component names in
  per component CPackRPM specific variables. E.g. component named
  "foo" now expects component specific variable to be
  "CPACK_RPM_FOO_PACKAGE_NAME" while before it expected
  "CPACK_RPM_foo_PACKAGE_NAME". Upper cased component name part in
  variables is compatible with convention used for other CPack
  variables. For back compatibility old format of variables is still
  valid and preferred if both versions of variable are set, but the
  preferred future use is upper cased component names in variables.
  New variables that will be added to CPackRPM in later versions will
  only support upper cased component variable format.
