POSIX specifies that two leading slashes have implementation-defined
interpretation, so CMake 3.31 and below did not normalize away leading
double slashes. However, most implementations simply treat a leading
`//` as just `/`, so CMake 4.0 now normalizes them away when they do not
correspond to a network path on Windows.
This change exposed that we were not normalizing `CMAKE_TOOLCHAIN_FILE`
before passing its value to `include()` the first time if it was not
passed with the `FILEPATH` or `PATH` cache entry type. Fix that.
Fixes: #27010
In commit 5aed3ee49d (cmSystemTools: Add GetLogicalWorkingDirectory,
2024-10-28, v4.0.0-rc1~528^2~6) we incorrectly trusted `PWD` to be a
normalized path so long as its realpath matches the current working
directory.
Fixes: #26870
This was accidentally dropped by commit 622596c6b2 (cmSystemTools:
Re-implement ToNormalizedPathOnDisk without translation map, 2024-10-30,
v4.0.0-rc1~528^2~5). Previously it was done by `CollapseFullPath`.
`cm::PathResolver` intentionally does not expand `~` because it makes
sense only for transforming input paths. Teach `ToNormalizedPathOnDisk`
to handle it directly.
Fixes: #26827
Add a `-LR[A][H] <regex>` flag with similar functionality to `-L[A][H]`,
but instead of listing all cached variables, it show only specific
variables that match the name regex.
- Depends on cppdap and jsoncpp.
- Add --debugger argument to enable the Debugger.
- Add --debugger-pipe argument for DAP traffics over named pipes.
- Support breakpoints by filenames and line numbers.
- Support exception breakpoints.
- Call stack shows filenames and line numbers.
- Show Cache Variables.
- Show the state of currently defined targets,
tests and directories with their properties.
- Add cmakeVersion to DAP initialize response.
- Include unit tests.

For policy-specific tests, use the version before the policy was
introduced. Otherwise, use 3.5 where possible.
Also, remove `cmake_minimum_required()` and `project()` calls from
individual cases where they are handled by `CMakeLists.txt`.
The fix in commit 08aa516880 (cmake: Stop parsing after `--` when
detecting script mode, 2022-12-06, v3.26.0-rc1~216^2) only corrected the
case where `-P -- -P <arg>` occurred and not `-P -- -P -<other>`.
Fixes: #24220
Modify most of the modules that ship with CMake to use the new
try_compile / try_run signatures added by commit aa9220d3a0
(try_compile: Add keyword-dispatched signature, 2022-09-02). This
improves debugging by each invocation using its own directory so that
the results of multiple invocations can be retained.
This does not cover any invocations which provide an entire project, as
that flavor of try_compile has not yet been updated.
When `cmake -E env` is given the `--modify` flag, try to parse the
following argument as an `ENVIRONMENT_MODIFICATION` operation and apply
it to the environment.
This generalizes `--unset=`:
1. When implementing `ENVIRONMENT_MODIFICATION` features for other CMake
commands, the `MYVAR=OP:VALUE` strings do not need to be translated
to OP-specific flags.
2. This provides a natural and consistent extension point to introduce
new operations without introducing very many flags.
3. Users need to learn only one syntax to access the same functionality.
There is one difference between the behavior here as compared to CTest's
interpretation of the `ENVIRONMENT_MODIFICATION` test property.
The `MYVAR=reset:` command when run in `cmake -E env` will reset `MYVAR`
to whatever its value was when `cmake -E env` launched, rather than try
to checkpoint after plain `MYVAR=VALUE` options. This makes `MYVAR=VALUE`
and `--modify MYVAR=set:VALUE` semantically equivalent.

The fix in commit e4f1b301fe (cmake: Allow arbitrary args passed to
CMake script, 2020-05-04, v3.18.0-rc1~211^2) only applied to "cache"
arguments like `-DFOO`. Extend the fix to allow arbitrary arguments
that collide with other CMake arguments like `-S` and `-B`.
