Clarify the release note added by commit 8ac826a5f2 (GenEx: Fix
evaluation of $<CONFIG> on imported targets, 2025-07-30,
v4.2.0-rc1~439^2) to more precisely describe the behavior change.
See: https://discourse.cmake.org/t/15251/2
* FindKDE4: Added note about KDE4_FOUND result variable (it is set by
the upstream FindKDE4Internal module, and now also synced in the docs
and code for consistency).
For the sake of completeness with other find modules, also the following
deprecated find modules are synced as they already provided these
variables:
* FindDart: Documented the Dart_FOUND result variable.
* FindUnixCommands: Updated documentation (documented UnixCommands_FOUND
result variable, and listed cache variables used by this module).
Issue: #27242
This adds the following new arrays, which together capture all direct
dependencies and interface dependencies of a target:
- linkLibraries
- interfaceLinkLibraries
- compileDependencies
- interfaceCompileDependencies
- objectDependencies
- orderDependencies
Fixes: #21995, #25213
When targeting the MSVC ABI, define `_MBCS` by default if the project
does not define `_SBCS` or `_UNICODE`. Visual Studio has long defined
one of the three character set macros automatically. For consistency,
define it when compiling for the MSVC ABI with other generators.
Add policy CMP0204 for compatibility.
Fixes: #27275
Avoid repeating almost identical information for every module.
Document the pattern of the change and refer the reader to individual
modules for details.
Visual Studio defines this automatically for `.dll` targets.
For consistency, define it when compiling for the MSVC ABI
with other generators. Add policy CMP0203 for compatibility.
Fixes: #27253
Changes:
- Added new `RESULT_VARIABLE` keyword to enable customizing the name of
the internal cache variable, which contains the boolean result of the
check.
- The macro check_type_size() changed to function for easier arguments
handling.
- Documentation synced and extended to better understand the
check_type_size() command. Some typos fixed in the initial example.
- CheckTypeSize tests adjusted so also C++ is tested.
- Error messages slightly adjusted when checking the LANGUAGE argument.
Closes: #27202
This marks all `<PACKAGENAME>_FOUND` result variables as deprecated
where possible (for `<PackageName>` find modules) to make it clearer
which variable to use.
In CMake 3.3, the FindPackageHandleStandardArgs module was refactored to
set both `<PackageName>_FOUND` and uppercase `<PACKAGENAME>_FOUND`
result variables to the same values. Before that, the FOUND_VAR argument
could be used to set the result variable.
* FindMatlab: Uppercased MATLAB_FOUND is not mentioned as it was never
documented.
* Documentation for FindPythonInterp and FindPythonLibs modules synced
accordingly to their deprecation (3.12 instead of 4.2).
* OPENGL_FOUND: deprecation version synced with other find modules.
* DevIL_FOUND was introduced in CMake 3.8. The uppercased variant not
mentioned as it was previously never documented.

Policy CMP0189, introduced by commit b3da9c6d60 (GenEx: Evaluate
LINK_LIBRARIES target properties transitively, 2025-02-24,
v4.1.0-rc1~731^2), takes effect at generation time, and so uses the
policy value as of the end of each directory. However, some projects
may rely on `file(GENERATE)` with the policy's OLD behavior in order
to extract targets' *direct* dependencies from `LINK_LIBRARIES`.
Pending a first-class solution to that problem, make it easier for
projects to port to the policy's NEW behavior in general while
retaining the OLD behavior in an isolated context.
Fixes: #27220
