In commit 84996a65aa (Unity: Add option to use relative paths for unity
files, 2024-10-15, v4.0.0-rc1~637^2) we added support for this variable
to initialize the `UNITY_BUILD_RELOCATABLE` target property, but forgot
to document it.
Issue: #26352
The `CMAKE_COMPILER_IS_*` variables have been documented as deprecated
since CMake 3.24, without emitting warnings. This commit updates their
documentation to help users safely migrate to `CMAKE_<LANG>_COMPILER_ID`
variables. Also a RST deprecation directive is added to clarify their
status.

Provide it whenever we can detect a target architecture from the
compiler during compiler inspection. In order to avoid changing
existing IDs, do this only for compilers where we don't already
detect a target architecture during compiler identification.
Fixes: #17702
- QNX C/C++ compiler is identified in `CMAKE_<LANG>_COMPILER_ID` as
value "QCC". The qcc/q++ are frontend compiler commands that invoke
the GNU compiler (gcc/g++) as a backend compiler, but it's treated as
a separate compiler with its own ID for better determination.
- The C/C++ compiler on UnixWare/OpenServer is identified in
`CMAKE_<LANG>_COMPILER_ID` as value "SCO", (compiler that defines the
`__SCO_VERSION__` preprocessor macro).
This adds a `CMAKE_FIND_REQUIRED` variable which causes `find_package`,
`find_path`, `find_file`, `find_library` and `find_program` to be
considered `REQUIRED` by default.
It also introduces an `OPTIONAL` keyword to those commands, allowing
them to ignore the value of this variable.
Issue: #26576
Extend commit 1a35351125 (Add CMAKE_POLICY_VERSION_MINIMUM to help
configure outdated projects, 2025-02-13, v4.0.0-rc1~12^2) with an
environment variable to initialize the cache entry. That will make it
easier to use when `cmake` is invoked under layers of scripting.
Closes: #26715
Provide packagers and end users with a way to try configuring projects that
have not been updated to set their policy version to a supported level.
Closes: #26698
This allows projects to use `if(AIX)` blocks instead of spelling
out `if(CMAKE_SYSTEM_NAME STREQUAL "AIX")`. We already have similar
variables for many other platforms.
Run the script:
Utilities/Sphinx/update_versions.py --since v3.31.0 --overwrite
Manually renumber `3.32` to `4.0` since the script is meant for
minor version increments. Also filter out changes to documents
that were added for long-existing variables.
Indenting a list relative to the previous paragraph creates
a blockquote. Combined with the natural list indent it results
in an overly large left margin.
Covers almost all blocks containing actual code, except:
* Parsed-literal blocks can't be highlighted, including many command
summaries and substitution-heavy docs like find_... commands.
This is a Sphinx limitation.
* Code with errors, like CMP0049, DEPLOYMENT_ADDITIONAL_FILES,
DEPLOYMENT_REMOTE_DIRECTORY, @PACKAGE_INIT@ substitution in the
tutorial, bracket arguments/comments in cmake-language.7 and
cmake-developer.7.
* FindQt4 module, which needs reformatting.
Replace our hard-coded default for `/RTC1` with a first-class
abstraction to select runtime checks from an enumeration of logical
names. Add a `MSVC_RUNTIME_CHECKS` target property and corresponding
`CMAKE_MSVC_RUNTIME_CHECKS` variable.
Removing the old default flag requires a policy because existing
projects may rely on string processing to edit them and choose
runtime checks under the old behavior. Add policy CMP0184 to
provide compatibility.

CMake now provides the CMAKE_<LANG>_LINK_MODE variable which specify how
the link step is done. So, the CMAKE_<LANG>_USING_LINKER_MODE variable
is no longer needed.
