Provide a standardized way to handle the C++ "standard" headers
customized to be used with current CMake C++ standard constraints.
Offer under directory `cm` headers which can be used as direct
replacements of the standard ones. For example:
#include <cm/string_view>
can be used safely for CMake development in place of the `<string_view>`
standard header.

Our logic that sets `ReferenceOutputAssembly` in `ProjectReference` has
accumulated a series of conditions for different cases in which the
referenced target has no output. Simplify the condition to check
`GetManagedType` directly for cases with no output.
This will explicitly turn off `ReferenceOutputAssembly` in
`ProjectReference` for utility (i.e. `add_custom_target`) and special
targets (i.e. `ZERO_CHECK`, etc.), and allowing reference of target
dependencies that produce some output.

The precompile header file will be added to the list of files,
and be part of the newly "Precompile Header File" source group.
Also make sure the sources have the header as dependency.
Evaluate and expand generator expressions in byproducts of custom commands.
Note that it is still not possible to use generator expressions in byproducts
of the commands `add_custom_command` and `add_custom_target`. These commands
still reject the input. This is a preparation step for OUTPUT generator
expression support.
Issue: #12877
Refactored internals of cmCustomCommandGenerator to make processing of path
lists (evaluation of generator expressions and expansion into a list) available
as AppendPaths utility function to be used for byproduct generator expression
support.
Custom command functions consist of two parts: setup and commit. Only the
commit part will be delayed to generate time. This change puts the commit part
of AddCustomCommandOldStyle into a lambda. When delayed, it will not be
possible to break the loop over the outputs if an error occurs which seems
reasonable.

The new `AUTOMOC_PATH_PREFIX` boolean target property enables automatic
generation of the path prefix `-p` option for `moc`.
`AUTOMOC_PATH_PREFIX` is initialized from the variable
`CMAKE_AUTOMOC_PATH_PREFIX`, which is ON by default.
When `AUTOMOC_PATH_PREFIX` is enabled, CMake tests if a `moc`ed header file is
in one of the include directories. If so, then the `-p` option, with the
relative path of the header parent directory to the respective include
directory, is added to the `moc` command. If the header file is not in an
include directory, the `-p` option is omitted.
Closes: #18815 "AUTOMOC: generated files include full relative path,
breaking certain reproducible builds"
This introduces the `cmQtAutoGenerator::MessagePath` method, that abbreviates
paths by placing a
- "SRC:" prefix in place of the project source directory
- "BIN:" prefix in place of the project binary directory
The method is used in `AUTO{MOC,UIC,RCC}` when paths are displayed in
messages. This makes the messages generated by `AUTO{MOC,UIC,RCC}` shorter
and improves their readability.
This splits the `JobEvalCacheT` job into separate `JobEvalCacheMocT` and
`JobEvalCacheUicT` classes, that run concurrently.
The `JobEvalCache*T::FindIncluded*` methods are overhauled to store probed
directoriy names only if probing fails. Warning messages are refactored
to show the file name and the probed directories instead of all probed file
paths. This is easier to read.
By splitting `JobProbeDepsT` into two independent `JobProbeDepsMocT`,
`JobProbeDepsUicT`, the moc and uic job generation will happen concurrently.
This should improve the execution speed, when both AUTOMOC and AUTOUIC are
enabled.
Parent directory names for moc and uic output files are are collected in
a `std::unordered_set<std::string>` and get created in a batch.
Beforehand we tried to create the parent directory for each output file.
This led to duplications of `MakeDirectory` calls when there were multiple
output files in the same directory (which is the case usually).
