The six tests/cmake_* integration-test wrappers had drifted:
- Only cmake_import and cmake_import_minver forwarded
-A "${CMAKE_GENERATOR_PLATFORM}" to the inner configure, and none
forwarded -T "${CMAKE_GENERATOR_TOOLSET}". The Windows workflow
configures the outer build with -A Win32 -T ClangCL, so without
forwarding, the inner projects of cmake_add_subdirectory,
cmake_fetch_content, cmake_fetch_content2 and
cmake_target_include_directories built with the generator defaults
instead of matching the outer build's platform and toolset. Forward
both consistently from all six wrappers.
- cmake_fetch_content and cmake_fetch_content2 passed
-Dnlohmann_json_source to their inner projects, which never read it
(CMake warns "manually-specified variables were not used"); the
inner projects fetch their own copy of the library instead. Drop it.
- tests/CMakeLists.txt set JSON_FORCED_GLOBAL_COMPILE_OPTIONS from the
matching environment variable but never read the cache variable
again; the lines right below it read $ENV{JSON_FORCED_GLOBAL_COMPILE_OPTIONS}
directly, like the LINK_OPTIONS counterpart already does. Remove the
dead set().
This changes which platform and toolset the Win32 and ClangCL CI jobs
build the four newly-forwarding wrappers' inner projects with, which
may surface new failures there; CI has to confirm those jobs.
Verified locally with Ninja (empty -A ""/-T "" is accepted): all 12
cmake_* tests still pass, and the inner fetch_content configures no
longer warn about the unused variable.
Closes#5714 item 6.

Starting with CMake 3.27, deprecation warnings are issued
when asking for policy settings for CMake 3.4 or earlier.
The cmake_minimum_required() command accepts a version
range, which allows NEW policy settings up to the upper end
of that range to be used, but without raising the minimum
CMake version above the bottom of that range. This means
NEW policy settings will be used where available, without
requiring them. This change updates the project's
cmake_minimum_required() calls to use a version range to
extend the upper policy version to 3.14 where it wasn't already
at that version or higher. This prevents the deprecation warning
from CMake 3.27, and gives breathing space before a future
CMake release will start issuing similar deprecation warnings
again.
* Add versioned inline namespace
Add a versioned inline namespace to prevent ABI issues when linking code
using multiple library versions.
* Add namespace macros
* Encode ABI information in inline namespace
Add _diag suffix to inline namespace if JSON_DIAGNOSTICS is enabled, and
_ldvcmp suffix if JSON_USE_LEGACY_DISCARDED_VALUE_COMPARISON is enabled.
* Move ABI-affecting macros into abi_macros.hpp
* Move std_fs namespace definition into std_fs.hpp
* Remove std_fs namespace from unit test
* Format more files in tests directory
* Add unit tests
* Update documentation
* Fix GDB pretty printer
* fixup! Add namespace macros
* Derive ABI prefix from NLOHMANN_JSON_VERSION_*
