The XXX_autogen targets are implemented as utility commands, which
means they always run, even if there weren't any changes.
For the Ninja generator and Qt >= 5.15 we're taking a different
approach: This commit adds custom commands that create
XXX_autogen/timestamp files. Those custom commands have a depfile
assigned that is generated from the depfiles that were created by moc.
The XXX_autogen targets merely wrap the XXX_autogen/timestamp custom
commands.
Fixes: #18749
In Qt version 5.15.0 moc learned to output the dependencies
of the generated file.
This commit enhances JobCompileMocT to read the dependency file
written by moc. The dependencies are stored in the same cache that's
used for the dependencies determined by dependency filters.
The dependency filter functionality is turned off if moc's dependency
output feature is used.

`rcc` generated files are not compatible with unity builds, because they
contain classes in anonymous namespaces and static data with identical names.
This patch sets the source file property `SKIP_UNITY_BUILD_INCLUSION` to `On`
on all `AUTORCC` generated files to exclude them from unity build files.
Fixes: #20191 "QT5: Exclude resource files from unity build"
Reintroduces .hh header processing in AUTOMOC and AUTOUIC based on the new
policy CMP0100 setting.
Fixes: #13904 CMAKE_AUTOMOC misses headers with ".hh" extension
In AUTOGEN, this changes the moc output file name computation on output name
conflicts to first try to add the header suffix to the moc output base name.
When that still conflicts, we try adding a range of sequential numbers.
If we still can't find an unique output name, we raise an error.
Since commit 4a9154537c (Autogen: Use cmake::IsHeader/SourceExtension
for file type detection, 2019-07-02, v3.16.0-rc1~470^2~4) we process
`.hh` files with `AUTOMOC`. However, this change can break existing
projects that do not expect the behavior. Revert it for now. It can
be restored later via a policy.
Fixes: #20101
Move custom command creation to cmLocalGenerator and dispatch custom
commands in cmMakefile to generate time. Generators add custom commands
using the new methods provided by cmLocalGenerator.
Issue: #12877
We used to store information for the _autogen target in a CMake script
file AutogenInfo.cmake, which was imported by a temporary cmake instance in
the _autogen target. This introduced the overhead of creating a temporary
cmake instance and inherited the limitations of the CMake language which
only supports lists.
This patch introduces JSON files to pass information to AUTORCC and
autogen_ targets. JSON files are more flexible for passing data, e.g. they
support nested lists.
The patch has the side effects that
- AutogenInfo.cmake is renamed to AutogenInfo.json
- AutogenOldSettings.txt is renamed to AutogenUsed.txt
- RCC<qrcBaseName><checksum>Info.cmake is renamed to
AutoRcc_<qrcBaseName>_<checksum>_Info.json
- RCC<qrcBaseName><checksum>.lock is renamed to
AutoRcc_<qrcBaseName>_<checksum>_Lock.lock
- RCC<qrcBaseName><checksum>Settings.txt is renamed to
AutoRcc_<qrcBaseName>_<checksum>_Used.txt
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.

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 removes code that sorts include directories for `AUTOMOC` according to
`CMAKE_INCLUDE_DIRECTORIES_PROJECT_BEFORE`. This is possible because the
included directories passed to `AUTOMOC` are already sorted, also with
respect to `CMAKE_INCLUDE_DIRECTORIES_PROJECT_BEFORE`.
This patch is generated by a python script that uses regular expressions to
search for string concatenation patterns of the kind
```
std::string str = <ARG0>;
str += <ARG1>;
str += <ARG2>;
...
```
and replaces them with a single `cmStrCat` call
```
std::string str = cmStrCat(<ARG0>, <ARG1>, <ARG2>, ...);
```
If any `<ARGX>` is itself a concatenated string of the kind
```
a + b + c + ...;
```
then `<ARGX>` is split into multiple arguments for the `cmStrCat` call.
If there's a sequence of literals in the `<ARGX>`, then all literals in the
sequence are concatenated and merged into a single literal argument for
the `cmStrCat` call.
Single character strings are converted to single char arguments for
the `cmStrCat` call.
`std::to_string(...)` wrappings are removed from `cmStrCat` arguments,
because it supports numeric types as well as string types.
`arg.substr(x)` arguments to `cmStrCat` are replaced with
`cm::string_view(arg).substr(x)`
This replaces invocations of
- `cmSystemTools::IsInternallyOn` with `cmIsInternallyOn`
- `cmSystemTools::IsNOTFOUND` with `cmIsNOTFOUND`
- `cmSystemTools::IsOn` with `cmIsOn`
- `cmSystemTools::IsOff` with `cmIsOff`
