Move some target related enumeration types from `cmStateTypes.h` to a
new header, as these really aren't "state" types. Also, make
`TargetType` a strongly-typed enumeration.
Add an --out-of-date option to ctest which runs only those tests with
recorded build dependencies whose timestamps are newer than the timestamp
at which the test last finished.
Fixes: #27614
Extend the test_prep/<test> and test_prep/all build targets, generated
from add_test(BUILD_DEPENDS) when CMAKE_TEST_BUILD_DEPENDS is enabled, to
the Makefile generators. Previously only the Ninja and FASTBuild
generators provided them.
Resolve each test's dependencies in a shared layer so all command-line
generators consume one result. cmTestGenerator now filters target
dependencies to build-system targets and records, for each file
dependency, the single target that produces it as a primary
custom-command output (cmGlobalGenerator::FindOutputOwningTarget). The
Makefile generators emit phony rules in CMakeFiles/Makefile2 depending on
<target>.dir/all, with top-level forwarding rules. Sharing the
resolution also stops Ninja and FASTBuild from emitting a dead test_prep
edge for a non-buildable (e.g. INTERFACE) BUILD_DEPENDS target.
On the Makefile generators a file dependency that no single target
produces, and a test whose name contains ':', cannot be expressed as a
recursive-make rule and are reported with a warning and skipped.
Fixes: #27879
Each Rust source file given to a target is considered a separate crate
root. There's a concept of a "main crate root", which is the `.rs` file
that is given to the final linker phase in CMake. Other Rust source file
in a target are built as rlib separately.
The project can still build `.rs` files into object files by setting the
Rust_EMIT property on the desired source file.
Some projects might get unlucky and have targets which collide in the
sha3-512 hash (truncated to 4) in a directory which also collides in the
same way (easily done by sharing it). Note such problems as potentially
colliding and offer potential remedies.
Also add a test which generates the error.
Closes: #27465
This commit extracts the set of parameters required to build a CMake
project into a dedicated class. While this class is currently just a
wrapper for the data, the goal is to eventually implement a validate()
method which verifies that a given configuration contains the minimum
set of information required to execute a build, and that any optional
options are compatible with one another.
The generator does a lot of tricks in order to make the "rebuild-bff"
target up-to-date immediately after the generation. We can skip all of
those during "TryCompile" runs, which should reduce configure time.
There's no control over the object base name implemented in the
FASTBuild generator. Rather than expecting some half-supported behavior,
just ignore it completely there.
Similarly, Xcode ends up making its own object paths internally
regardless of what CMake would like.
The property settings set things up once, but nothing ensures that
post-reuse hookup that any property changes propagate. Instead, when
computing PDB information, if PCH reuse is enabled, just always use its
values.
Also drop enforcement at generate time of property value consistency as
it is now ignored when PCH reuse is in effect.
Additionally, if a target is PCH-reused, generate a PDB output directory
for it.
The `PchReuseFromIgnoreOwnProps` test failed previously because the
post-reuse link update of the consuming `PDB` properties are no longer
considered. The `PchReuseFromUseUpdatedProps` failed because the
post-reuse link did not update the copy of the properties added to
consuming reuse target properties.
Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`, now with "east const" enforcement.
Use `clang-format` version 18.

Issue: #26123
Rerun CMake when `cmake_install.cmake` or `CTestTestfile.cmake` are out
of date. This enables regeneration if a subdirectory is removed before
invoking `ninja`.
