For special properties like `INCLUDE_DIRECTORIES`, the pointer returned
by `cmTarget::GetProperty` is only valid until the next time the same
special property is queried on *any* target. When evaluating a nested
`TARGET_PROPERTY` generator expression we may look up such a property
more than once on different targets. Fix `TargetPropertyNode::Evaluate`
to store the lookup result in locally owned memory earlier.
Fixes: #19286
Add a `CMAKE_FIND_PACKAGE_PREFER_CONFIG` variable to tell
`find_package` calls to look for a package configuration file
first even if a find module is available.
Fixes: #16805, #19236
Previously code like
file(REMOVE_RECURSE "${accidentally_missing_variable}")
treated the empty string as a relative path with respect to the
current directory and removed its contents. Change this behavior
to ignore the empty string with a warning instead.
Normally such behavior changes are done with a policy, but in this case
such code is likely a real bug in project code that can delete data.
Fixes: #19274

This adds a subdirectory to the MakeClean test, in which files are added to
the `ADDITIONAL_CLEAN_FILES` directory property, but which holds no targets.

4edc0ef359 Test: Improve WarnUnusedCliUnused to run on all generators
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !3328
In the WarnUnusedCliUnused test, the whole CMakeCache.txt was removed in the
clean stage to trigger the same CMake warning in re-builds. This technique
worked only in the Makefile generators and the test was limited to these.
Now only the variable of interest is removed from the cache by using a
`unset(UNUSED_CLI_VARIABLE CACHE)` statement in the CMakeLists.txt file.
This makes the WarnUnusedCliUnused test run on all generators

Provide a way for custom commands and targets to set the pool variable
of the ninja build statement. Setting `JOB_POOL` is not compatible with
`USES_TERMINAL`, which implies the `console` pool.
The option is silently ignored with other generators.

This class is ultimately intended as a replacement for cmsys::Process.
It spawns a series of processes using libuv, piping the output of each
command into the next.
Note: input support has not yet been implemented because write
support has not yet been implemented on cmUVStreambuf.
