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.

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.
Since commit v3.0.0-rc1~260^2~14 (ctest: Make the --build-makeprogram
optional for --build-and-test, 2013-11-14), binary dictionary is also
required to run CTest given the option `--build-nocmake`.
Replace use of cmsys::auto_ptr with a CM_AUTO_PTR macro that maps to
our own implementation adopted from the KWSys auto_ptr implementation.
Later we may be able to map CM_AUTO_PTR to std::auto_ptr on compilers
that do not warn about it.
Automate the client site conversions:
git grep -l auto_ptr -- Source/ | grep -v Source/kwsys/ | xargs sed -i \
's|cmsys::auto_ptr|CM_AUTO_PTR|;s|cmsys/auto_ptr.hxx|cm_auto_ptr.hxx|'
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.
This property allow to specify a specific Visual Studio tool for a
source file overriding the default tool behavior. For example, a
`.resw` file being processed as a `PriResource` file. This has the
advantage of being able to teach CMake to process new file types without
code modifications.
Even in relatively small projects using `--trace` (and `--trace-expand`)
may produce a lot of output. When developing a custom module usually
one is interested in output of only a few particular modules.
Add a `--trace-source=<file>` option to enable tracing only a subset of
source files. The final output would be only from requested modules,
ignoring anything else not matched to given filename(s).
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 ``FIND_LIBRARY_USE_LIB32_PATHS`` global property analogous to the
``FIND_LIBRARY_USE_LIB64_PATHS`` property. This helps find commands on
multilib systems that use ``lib32`` directories and either do not have
``lib`` symlinks or point ``lib`` to ``lib64``.
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.
The `--build` mode was confusingly documented among other options,
falsely implying that it can be used anywhere on the command line.
Move the documentation to a dedicated section and clarify its usage
as s separate command line mode.
In Sphinx output formats that print the toctree the policy numbers in
links from the cmake-policies(7) manual are not descriptive. Convert
the toctree entries to cross-reference syntax and add the summary of
each policy. For now simply duplicate the policy summary line. We
already maintain copies in `cmPolicies.h` and `Help/policy/*.rst` docs.
Versions below 12.1 do not provide enough information to properly detect
if compiling with c++98 or c++0x enabled so remove them from the
supported list.
