I am proud to announce that CMake 3.7.0 is now available for download at:
https://cmake.org/download/
Documentation is available at:
https://cmake.org/cmake/help/v3.7
Release notes appear below and are also published at
https://cmake.org/cmake/help/v3.7/release/3.7.html
Some of the more significant changes in CMake 3.7 are:
* CMake now supports Cross Compiling for Android with simple
toolchain files.
* The "Ninja" generator learned to conditionally support Fortran
when using a "ninja" tool that has the necessary features. See
generator documentation for details.
* The "if()" command gained new boolean comparison operations
"LESS_EQUAL", "GREATER_EQUAL", "STRLESS_EQUAL", "STRGREATER_EQUAL",
"VERSION_LESS_EQUAL", and "VERSION_GREATER_EQUAL".
* The "try_compile()" command source file signature now honors
configuration-specific flags (e.g. "CMAKE_<LANG>_FLAGS_DEBUG") in
the generated test project. Previously only the default such flags
for the current toolchain were used. See policy "CMP0066".
* "Toolchain files" may now set "CMAKE_EXE_LINKER_FLAGS_INIT",
"CMAKE_SHARED_LINKER_FLAGS_INIT", and
"CMAKE_MODULE_LINKER_FLAGS_INIT" variables to initialize the
"CMAKE_EXE_LINKER_FLAGS", "CMAKE_SHARED_LINKER_FLAGS", and
"CMAKE_MODULE_LINKER_FLAGS" cache entries the first time a language
is enabled in a build tree.
* CTest now supports test fixtures through the new "FIXTURES_SETUP",
"FIXTURES_CLEANUP" and "FIXTURES_REQUIRED" test properties. When
using regular expressions or "--rerun-failed" to limit the tests to
be run, a fixture's setup and cleanup tests will automatically be
added to the execution set if any test requires that fixture.
* 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* Visual Studio 7.1 and 2005 -- superseded by VS 2008 and above
* MinGW.org mingw32 -- superseded by MSYS2 mingw32 and mingw64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.
CMake 3.7 Release Notes
***********************
Changes made since CMake 3.6 include the following.
New Features
============
Platforms
---------
* CMake now supports Cross Compiling for Android with simple
toolchain files.
* The Clang compiler is now supported on AIX.
Generators
----------
* The "Ninja" generator learned to conditionally support Fortran
when using a "ninja" tool that has the necessary features. See
generator documentation for details.
* The "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
Makefile Generators.
* The "Visual Studio 15" generator was added. This is experimental
and based on Preview 4 because this version of VS has not been
released.
* Visual Studio Generators for VS 2010 and above learned to place
".natvis" source files into VS project files properly.
* The "Xcode" generator's rudimentary Swift language support learned
to honor a new "CMAKE_Swift_LANGUAGE_VERSION" variable to tell Xcode
what version of Swift is used by the source.
* The "CodeLite" generator gained a new "CMAKE_CODELITE_USE_TARGETS"
option to change project creation from projects to targets.
Commands
--------
* The "add_custom_command()" command gained a new "DEPFILE" option
that works with the "Ninja" generator to provide implicit dependency
information to the build tool.
* The "cmake_parse_arguments()" command gained a new "PARSE_ARGV"
mode to read arguments directly from "ARGC" and "ARGV#" variables
inside a "function()" body.
* The "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 "file(DOWNLOAD)" and "file(UPLOAD)" commands gained
"HTTPHEADER <HTTP-header>" and "USERPWD <username>:<password>"
options.
* The "find_library()" and "find_package()" commands learned to
search in "lib32/" directories when the build targets a 32-bit
architecture. See the "FIND_LIBRARY_USE_LIB32_PATHS" global
property.
* The "find_package()" command gained the possibility of sorting
compatible libraries by "NAME" or by "NATURAL" sorting by setting
the two new variables "CMAKE_FIND_PACKAGE_SORT_ORDER" and
"CMAKE_FIND_PACKAGE_SORT_DIRECTION".
* The "if()" command gained new boolean comparison operations
"LESS_EQUAL", "GREATER_EQUAL", "STRLESS_EQUAL", "STRGREATER_EQUAL",
"VERSION_LESS_EQUAL", and "VERSION_GREATER_EQUAL".
* The "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 "string(TIMESTAMP)" and "file(TIMESTAMP)" commands gained
support for the "%a" and "%b" placeholders. These are the
abbreviated weekday and month names.
* The "try_compile()" command source file signature now honors
configuration-specific flags (e.g. "CMAKE_<LANG>_FLAGS_DEBUG") in
the generated test project. Previously only the default such flags
for the current toolchain were used. See policy "CMP0066".
Variables
---------
* Variable "CMAKE_FIND_PACKAGE_SORT_ORDER" was added to control the
sorting mode of the "find_package()" command.
* Variable "CMAKE_FIND_PACKAGE_SORT_DIRECTION" was added to control
the sorting direction the "find_package()" command.
* "Toolchain files" may now set a "CMAKE_<LANG>_FLAGS_INIT" variable
to initialize the "CMAKE_<LANG>_FLAGS" cache entry the first time a
language is enabled in a build tree.
* "Toolchain files" may now set "CMAKE_EXE_LINKER_FLAGS_INIT",
"CMAKE_SHARED_LINKER_FLAGS_INIT", and
"CMAKE_MODULE_LINKER_FLAGS_INIT" variables to initialize the
"CMAKE_EXE_LINKER_FLAGS", "CMAKE_SHARED_LINKER_FLAGS", and
"CMAKE_MODULE_LINKER_FLAGS" cache entries the first time a language
is enabled in a build tree.
Properties
----------
* On Apple platforms the "BUNDLE_EXTENSION" target property now also
applies to Frameworks and App Bundles.
* A "BINARY_DIR" directory property was added to get the absolute
path to the binary directory corresponding to the source directory
on which the property is read.
* A "BUILDSYSTEM_TARGETS" directory property was added to get the
list of logical buildsystem target names added by the project in a
directory.
* A "LINK_WHAT_YOU_USE" target property and supporting
"CMAKE_LINK_WHAT_YOU_USE" variable were introduced to detect (on
UNIX) shared libraries that are linked but not needed by running
"ldd -r -u".
* A "SOURCE_DIR" directory property was added to get the absolute
path to the source directory associated with a directory.
* A "SUBDIRECTORIES" directory property was added to get the list of
subdirectories added by a project in a directory.
* A "VS_SDK_REFERENCES" target property was added to tell Visual
Studio Generators to reference the named SDKs.
* A "VS_TOOL_OVERRIDE" source file property was created to tell
Visual Studio Generators what tool to use for a source file.
* The "WINDOWS_EXPORT_ALL_SYMBOLS" target property now applies to
executable targets with the "ENABLE_EXPORTS" property set.

CTest
-----
* CTest now supports test fixtures through the new "FIXTURES_SETUP",
"FIXTURES_CLEANUP" and "FIXTURES_REQUIRED" test properties. When
using regular expressions or "--rerun-failed" to limit the tests to
be run, a fixture's setup and cleanup tests will automatically be
added to the execution set if any test requires that fixture.
* The "ctest_configure()", "ctest_build()", "ctest_test()",
"ctest_coverage()", and "ctest_upload()" commands gained a new
"CAPTURE_CMAKE_ERROR" option to capture any errors that occur as the

"CPackProductBuild" module.
* CPack gained a new "CPACK_PACKAGE_CHECKSUM" variable to enable
generation of a checksum file for each package file.

installer.
* The "CPackRPM" module learned to generate debuginfo packages on
demand. See "CPACK_RPM_DEBUGINFO_PACKAGE" and its per component
version.

"CPACK_WIX_SKIP_PROGRAM_FOLDER" to allow specification of a custom
absolute installation prefix outside of the ProgramFiles folders.
