Expose the binutils' machine name (typically used as a prefix on the
tool names) publicly. This is expected to match the `gcc -dumpmachine`
value.

The NDK provides prebuilt toolchain files in directories named for the
host architecture. The NDK build system calls this `HOST_TAG`.
Expose the value publicly for use by clients that need to pass it
to external tools.
Suggested-by: Ruslan Baratov <ruslan_baratov@yahoo.com>
When this variable is not set by the user or toolchain file, set it to
the default selected. This will be useful for client code that needs to
pass the value to an external tool that needs to find the same toolchain
in the NDK. Leave it empty for a standalone toolchain.

Visual Studio provides toolchains that are themselves built for 32-bit
or 64-bit host architectures. By default it uses the 32-bit tools, but
it can be told to prefer the 64-bit tools on 64-bit hosts. Extend the
`CMAKE_GENERATOR_TOOLSET` specification to provide a way to request
use of the 64-bit host tools.
Closes: #15622
Create a `CMAKE_SUBLIME_TEXT_2_EXCLUDE_BUILD_TREE` variable to control

80574a38 Codelite: Consume the CMAKE_CODELITE_USE_TARGETS setting globally

Users may need to add custom `RPATH` entries to be able to run binaries
from their build tree without setting `LD_LIBRARY_PATH`. Provide a way
to do this that does not affect the install-tree `RPATH`.
The basic codelite generator creates .project files based on the
`project()` stanza. Add a `CMAKE_CODELITE_USE_TARGETS` option to use
the targets instead.
Create a new CMAKE_Swift_LANGUAGE_VERSION variable to specify the
SWIFT_VERSION attribute in a generated Xcode project. Ideally this
would be a `<LANG>_STANDARD` property but since Swift support is
very minimal we should reserve that property for more complete

Issue: #16326
Add `CMAKE_FIND_PACKAGE_SORT_{ORDER,DIRECTION}` variables to specify
sort order and direction.
When multiple package with the same name have been found in the same
location sorting option can be used to force a specific version to be
loaded (e.g. libA_1.12.0 instead of libA_1.1.0). Currently sorting by
NAME and by NATURAL order have been implemented.
Natural ordering makes use of the `strverscmp(3)` ordering.
Call the generator "Visual Studio 15" without any year because the
preview version of VS 15 does not provide a year in the product name.
Copy cmGlobalVisualStudio14Generator to cmGlobalVisualStudio15Generator
and update version numbers accordingly. Add the VS15 enumeration value.
Note that we do not need to add a MSVC15 variable or v150 toolset
because Visual Studio 15 comes with an updated version of the v140
toolset and remains ABI-compatible.
Teach tests VSExternalInclude, RunCMake.GeneratorPlatform, and
RunCMake.GeneratorToolset to treat VS 15 as they do VS 10-14.
Closes: #16143
CMake now supports cross compiling for Android using the NDK or a
standalone toolchain. Document the associated variables and how how to
write toolchain files for Android.
Document these variables.
Change our convention for setting these variables from:
set(CMAKE_EXE_LINKER_FLAGS_INIT "...")
to
string(APPEND CMAKE_EXE_LINKER_FLAGS_INIT " ...")
so that any value previously set by a toolchain file will be used.
Document these variables.
Change our convention for setting these variables from:
set(CMAKE_C_FLAGS_INIT "...")
to
string(APPEND CMAKE_C_FLAGS_INIT " ...")
so that any value previously set by a toolchain file will be used.
Automate the conversion with:
sed -i 's/set *(\(CMAKE_\(C\|CXX\|Fortran\|RC\|ASM\|${[^}]\+}\)_FLAGS\(_[^_]\+\)\?_INIT \+"\)/string(APPEND \1 /' \
Modules/Compiler/*.cmake Modules/Platform/*.cmake
and follow up with some manual fixes (e.g. to cases that already
meant to append). Also revert the automated changes to contexts
that are not protected from running multiple times.
In the `try_compile` source file signature we propagate the caller's
value of `CMAKE_<LANG>_FLAGS` into the test project. Extend this to
propagate `CMAKE_<LANG>_FLAGS_<CONFIG>` too instead of always using the
default value in the test project. This will be useful, for example, to
allow the MSVC runtime library to be changed (e.g. `-MDd` => `-MTd`).
However, some projects may currently depend on this not being done,
so we need to activate the behavior using a policy.
This change was originally made by commit v3.6.0-rc1~160^2 (try_compile:
Honor CMAKE_<LANG>_FLAGS_<CONFIG> changes, 2016-04-11) but without the
policy and so had to be reverted during the 3.6 release candidate cycle.
Fixes#16174.
Create a LINK_WHAT_YOU_USE target property and corresponding
CMAKE_LINK_WHAT_YOU_USE variable to enable this behavior.
Extend link commands by running `ldd -u -r` to detect shared
libraries that are linked but not needed.
Add a `CMAKE_TRY_COMPILE_PLATFORM_VARIABLES` variable to specify a list
of custom variables to be forwarded to a `try_compile` test project.
This will be useful for platform information modules or toolchain files
to forward some platform-specific set of variables from the host project
(perhaps set in its cache) to the test project so that it can build the
same way.
Create a `CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES` variable to specify
system include directories for for `<LANG>` compiler command lines.
This plays a role for include directories as the existing
`CMAKE_<LANG>_STANDARD_LIBRARIES` variable does for link libraries.
Add a `CMAKE_NINJA_OUTPUT_PATH_PREFIX` variable. When it is set, CMake
generates a `build.ninja` file suitable for embedding into another ninja
project potentially generated by an alien generator.
Create a <LANG>_CLANG_TIDY target property (initialized by a
CMAKE_<LANG>_CLANG_TIDY variable) to specify a clang-tidy command line
to be run along with the compiler.

06b310b5 cmCTestGIT: add an option to initialize submodules on update
56c1ea40 cmCTestGIT: fix git version references
Currently, CTest will not initialize any submodules within the already
checked out source tree. Add an option to do so. The use case for not
doing so is that some submodules may not be necessary for the current
test and keeping network usage down may be important.
Create a `CMAKE_TRY_COMPILE_TARGET_TYPE` option to specify use
of `add_library(... STATIC ...)` for the generated test project.
This will be useful for cross-compiling toolchains that cannot
link a binary without custom flags or scripts.
Since commit v3.4.0-rc1~5^2~1 (VS: Add support for selecting the Windows
10 SDK, 2015-09-30) the VS 2015 generator requires a Windows 10 SDK to
be available when CMAKE_SYSTEM_VERSION specifies Windows 10 (e.g. when
building on a Windows 10 host). Howewver, it is possible to install VS
2015 without any Windows 10 SDK. Instead of failing with an error
message about the lack of a Windows 10 SDK, simply tolerate this case
and use the default Windows 8.1 SDK. Since building for Windows Store
still requires the SDK, retain the diagnostic in that case.
This patch solves the problem of installing both: Device and Simulator
libraries on iOS. Before only one of them was installed.
If the IOS_INSTALL_COMBINED property is set on a target, a
special install hook will be activated which builds the corresponding
target and combines both at the install location.
The original patch was contributed by Ruslan Baratov, and polished by
Gregor Jasny.
Explicitly enable deprecated warnings by default, via the
cmake::GetSuppressDeprecatedWarnings method, which signals
suppression is turned off unless the CMake variables are set
as required.
Add tests and update the documentation for the new
functionality.
Make the documentation for the 'CMAKE_ERROR_DEPRECATED' CMake
variable consistent with the documentation for the
'CMAKE_WARN_DEPRECATED' CMake variable, in terms of wording.
Add 'deprecated' warning options type, to allow setting
CMAKE_WARN_DEPRECATED via the -W '-Wdeprecated' and
'-Wno-deprecated' options.
Add tests for new options and updated documentation.
Teach the VS 2015 generator to produce a WindowsTargetPlatformVersion
value. Use the CMAKE_SYSTEM_VERSION to specify the version and if not
set choose a default based on available SDKs. Activate this behavior
when targeting Windows 10.
Co-Author: Brad King <brad.king@kitware.com>
Teach CMakeDetermineSystem to check for a CMAKE_SYSTEM_VERSION setting
even when CMAKE_SYSTEM_NAME is not set. This will allow builds on the
host OS to target other versions of the OS without full cross-compiling.
The changes in commit c96fe0b4 (cmake: Add -W options to control
deprecation warnings and errors, 2015-07-28) fail to account for
-Wdev warnings produced by places in CMake other than message().
This causes a regression in which -Wno-dev fails to suppress such
warnings. Revert the feature until it can be revised accordingly.
Add documentation and tests for the existing
CTEST_CUSTOM_MAXIMUM_PASSED_TEST_OUTPUT_SIZE
CTEST_CUSTOM_MAXIMUM_FAILED_TEST_OUTPUT_SIZE
CTest variables.
Improve formatting, primarily by:
* Adding links to relevant commands, properties, generators, and so on.
* Converting code, symbols, paths, and so on to fixed-width fonts.
* Hard wrapping lines to 80 characters or less.
Use the CMAKE_LINK_SEARCH_START_STATIC and CMAKE_LINK_SEARCH_END_STATIC
variables to initialize the LINK_SEARCH_START_STATIC and
LINK_SEARCH_END_STATIC target properties respectively.
Refactor the -Wdev and -Wno-dev to use a generic -W parser that follows
the GCC pattern. Include support for setting CMAKE_ERROR_DEPRECATED and
CMAKE_WARN_DEPRECATED via the deprecated warning. Add -Werror=dev and
-Wno-error=dev options so that dev warning options are in line with
deprecated warning options. Use a new CMAKE_SUPPRESS_DEVELOPER_ERRORS
internal cache entry to store the above new dev options persistently.
Add tests for new options and updated cmake documentation and release
notes to list new options.
The --trace option is helpful, but sometimes, what you're looking for is
deep under many layers of function calls and figuring out what instance
of the function call you're looking at is tedious to determine (usually
involving patching and message()). Instead, add a --trace-expand option
to trace while expanding commands into what CMake actually sees.
Add variable CTEST_CHANGE_ID to configure the setting. This allows
CTest clients to give CDash information about what change is being
tested so that CDash can take actions to report the results (e.g. to a
pull request page).
Extend the Nsight Tegra project generator to add bunch of properties
with the backing variables to fine-tune the generated projects.
Add target properties that map to all "Configuration" PropertyGroups for
each configuration:
* ANDROID_ARCH
* ANDROID_STL_TYPE
Add target properties that map to the AntBuild section of vcxproj files:
* ANDROID_ANT_ADDITIONAL_OPTIONS
* ANDROID_ASSETS_DIRECTORIES
* ANDROID_JAR_DEPENDENCIES
* ANDROID_JAR_DIRECTORIES
* ANDROID_JAVA_SOURCE_DIR
* ANDROID_NATIVE_LIB_DEPENDENCIES
* ANDROID_NATIVE_LIB_DIRECTORIES
* ANDROID_PROCESS_MAX

Create a <LANG>_COMPILER_LAUNCHER target property (initialized by a
CMAKE_<LANG>_COMPILER_LAUNCHER variable) to specify a compiler launcher
tool. This will supersede the CMAKE_<LANG>_COMPILER_ARG1 approach to
using such tools. The old approach set CMAKE_<LANG>_COMPILER to the
launcher tool while the new approach leaves this variable set to the
actual compiler.
Implement this property for Makefile and Ninja generators. It cannot be
implemented for VS or Xcode generators as the IDE build tools offer no
such hooks.
The test for this variable was removed in commit v2.8.8~330^2~7 (complex:
Remove ancient unused ComplexRelativePaths test, 2011-12-23).
Commit v3.1.0-rc1~425^2~2 (backtrace: Convert to local paths in
IssueMessage, 2014-03-12) appears to have accidentally made some backtraces
print relative paths with the variable because conversions which used to be
done at configure time, before the variable had an effect are now potentially
done at generate time.
The documentation of the variable says not to use it, and the docs are wrong in
that the variable actually applies in per-directory scope.
The read of the variable makes it harder to split conversion methods from
cmLocalGenerator where they don't belong. Remove it now.
Create a <LANG>_INCLUDE_WHAT_YOU_USE target property (initialized by a
CMAKE_<LANG>_INCLUDE_WHAT_YOU_USE variable) to specify an IWYU command

882f48e5 Link libraries by full path even in implicit directories
318cd370 Help: Add link target for Find Modules section of cmake-developer.7
1535dcd8 Tests: Teach RunCMake to optionally merge command output to stdout
When CMP0003 was first introduced we wanted to link all libraries by
full path. However, some projects had problems on platforms where
find_library would find /usr/lib/libfoo.so when the project really
wanted to link to /usr/lib/<arch>/libfoo.so and had been working by
accident because pre-CMP0003 behavior used -lfoo to link.
We first tried to address that in commit v2.6.0~440 (Teach find_library
to avoid returning library paths in system directories, 2008-01-23) by
returning just "foo" for libraries in implicit link directories. This
caused problems for projects expecting find_library to always return a
full path. We ended up using the solution in commit v2.6.0~366 (...
switch library paths found in implicit link directories to use -l,
2008-01-31). However, the special case for libraries in implicit link
directories has also proven problematic and confusing.
Introduce policy CMP0060 to switch to linking all libraries by full path
even if they are in implicit link directories. Explain in the policy
documentation the factors that led to the original approach and now to
this approach.
